-1. Collator::getAvailableLocales().
-Return the locales available at the time of the call, including registered locales.
-If a sever error occurs (such as out of memory condition) this will return null.
-If there is no locale data, an empty enumeration will be returned. 
-Returned locales list is a strings in format of RFC4646 standart (see http://www.rfc-editor.org/rfc/rfc4646.txt).
-Examle of locales format: 'en_US', 'ru_UA', 'ua_UA' (see http://demo.icu-project.org/icu-bin/locexp).

-2. Collator::getDisplayName( $obj_locale, $disp_locale ).
-Get name of the object for the desired Locale, in the desired language. Both arguments 
-must be from getAvailableLocales method.
-
-     @param  string  $obj_locale   Locale to get display name for.
-     @param  string  $disp_locale  Specifies the desired locale for output
-
-Both parameters are case insensitive.
-For locale format see RFC4647 standart in ftp://ftp.rfc-editor.org/in-notes/rfc4647.txt
-
-3. Collator::getLocaleByType( $type ).
-Allow user to select whether she wants information on requested, valid or actual locale.
-Returned locale tag is a string formatted to a RFC4646 standart and normalize to normal form -
-value is a string from 
-For example, a collator for "en_US_CALIFORNIA" was requested. In the current state of ICU (2.0), 
-the requested locale is "en_US_CALIFORNIA", the valid locale is "en_US" (most specific locale 
-supported by ICU) and the actual locale is "root" (the collation data comes unmodified from the UCA) 
-The locale is considered supported by ICU if there is a core ICU bundle for that locale (although 
-it may be empty). 
-
-
-4. VariableTop
-The Variable_Top attribute is only meaningful if the Alternate attribute is not set to NonIgnorable.
-In such a case, it controls which characters count as ignorable. The string value specifies 
-the "highest" character (in UCA order) weight that is to be considered ignorable.
-Thus, for example, if a user wanted whitespace to be ignorable, but not any visible characters, 
-then s/he would use the value Variable_Top="\u0020" (space). The string should only be a 
-single character. All characters of the same primary weight are equivalent, so 
-Variable_Top="\u3000" (ideographic space) has the same effect as Variable_Top="\u0020".
-This setting (alone) has little impact on string comparison performance; setting it lower or higher
-will make sort keys slightly shorter or longer respectively.
-
-
-5. Strength
-The ICU Collation Service supports many levels of comparison (named "Levels", but also
-known as "Strengths"). Having these categories enables ICU to sort strings precisely
-according to local conventions. However, by allowing the levels to be selectively
-employed, searching for a string in text can be performed with various matching
-conditions.
-Performance optimizations have been made for ICU collation with the default level
-settings. Performance specific impacts are discussed in the Performance section below.
-Following is a list of the names for each level and an example usage:
-
-1. Primary Level: Typically, this is used to denote differences between base characters
-(for example, "a" < "b"). It is the strongest difference. For example, dictionaries are
-divided into different sections by base character. This is also called the level1
-strength.
-
-2. Secondary Level: Accents in the characters are considered secondary differences (for
-example, "as" < "as" < "at"). Other differences between letters can also be considered
-secondary differences, depending on the language. A secondary difference is ignored
-when there is a primary difference anywhere in the strings. This is also called the
-level2 strength.
-Note: In some languages (such as Danish), certain accented letters are considered to
-be separate base characters. In most languages, however, an accented letter only has a
-secondary difference from the unaccented version of that letter.
-
-3. Tertiary Level: Upper and lower case differences in characters are distinguished at the
-tertiary level (for example, "ao" < "Ao" < "ao"). In addition, a variant of a letter differs
-from the base form on the tertiary level (such as "A" and " "). Another ? example is the
-difference between large and small Kana. A tertiary difference is ignored when there is
-a primary or secondary difference anywhere in the strings. This is also called the level3
-strength.
-
-4. Quaternary Level: When punctuation is ignored (see Ignoring Punctuations ) at level
-13, an additional level can be used to distinguish words with and without punctuation
-(for example, "ab" < "a-b" < "aB"). This difference is ignored when there is a primary,
-secondary or tertiary difference. This is also known as the level4 strength. The
-quaternary level should only be used if ignoring punctuation is required or when
-processing Japanese text (see Hiragana processing).
-
-5. Identical Level: When all other levels are equal, the identical level is used as a
-tiebreaker. The Unicode code point values of the NFD form of each string are
-compared at this level, just in case there is no difference at levels 14
-. For example, Hebrew cantillation marks are only distinguished at this level. This level should be
-used sparingly, as only code point values differences between two strings is an
-extremely rare occurrence. Using this level substantially decreases the performance for
-both incremental comparison and sort key generation (as well as increasing the sort
-key length). It is also known as level 5 strength.
-
-For example, people may choose to ignore accents or ignore accents and case when searching
-for text. Almost all characters are distinguished by the first three levels, and in most
-locales the default value is thus Tertiary. However, if Alternate is set to be Shifted,
-then the Quaternary strength can be used to break ties among whitespace, punctuation, and
-symbols that would otherwise be ignored. If very fine distinctions among characters are required,
-then the Identical strength can be used (for example, Identical Strength distinguishes
-between the Mathematical Bold Small A and the Mathematical Italic Small A.). However, using
-levels higher than Tertiary the Identical strength result in significantly longer sort
-keys, and slower string comparison performance for equal strings.
-
-
-
-6. Collator::__construct( $locale ).
-The Locale attribute is typically the most important attribute for correct sorting and matching,
-according to the user expectations in different countries and regions. The default UCA
-ordering will only sort a few languages such as Dutch and Portuguese correctly ("correctly"
-meaning according to the normal expectations for users of the languages).
-Otherwise, you need to supply the locale to UCA in order to properly collate text for a
-given language. Thus a locale needs to be supplied so as to choose a collator that is correctly
-tailored for that locale. The choice of a locale will automatically preset the values for
-all of the attributes to something that is reasonable for that locale. Thus most of the time the
-other attributes do not need to be explicitly set. In some cases, the choice of locale will make a
-difference in string comparison performance and/or sort key length.
-In short attribute names, <language>_<script>_<region>_<keyword>.
-Not all the elements are required. Valid values for locale elements are general valid values
-for RFC4646 locale naming, and RFC 4647 lookup algorithm.
-Example:
-Locale="sv" (Swedish) "Kypper" < "Kopfe"
-Locale="de" (German) "Kopfe" < "Kypper"
-
-
-7. Collator::get/setAttribute.
-ICU uses UCA as a default starting point for ordering. Not all languages have sorting sequences
-that correspond with the UCA because UCA cannot simultaneously encompass the specifics of all
-the languages currently in use. Therefore, ICU provides a data-driven, flexible, and run-time
-customizable mechanism called "tailoring". Tailoring overrides the default order of code points
-and the values of the ICU Collation Service attributes.
-Collator have followed attributes:
-   - FRENCH_COLLATION, possible values are: 
-	ON
-	OFF (default)
-	DEFAULT
-
-   - CASE_FIRST, possible values are:
-	OFF (default)
-	LOWER_FIRST
-	UPPER_FIRST
-	DEFAULT
-
-   - CASE_LEVEL, possible values are:
-	OFF (default)
-	ON
-	DEFAULT
-
-   - NORMALIZATION_MODE, possible values are:
-	OFF (default)
-	ON
-	DEFAULT
-
-   - STRENGTH, possible values are:
-	PRIMARY
-	SECONDARY
-	TERTIARY (default)
-	QUATERNARY
-	IDENTICAL
-	DEFAULT
-
-   - ALTERNATE_HANDLING, possible values are:
-	NON_IGNORABLE (default)
-	SHIFTED
-	DEFAULT
-
-   - HIRAGANA_QUATERNARY_MODE, possible values are:
-	ON
-	OFF (default)
-	DEFAULT
-
-   - NUMERIC_COLLATION, possible values are:
-	ON
-	OFF (default)
-	DEFAULT
-
-Description of all of this attributes:
-
-FRENCH_COLLATION - Sort strings with different accents from the back of the string. This attribute
-is automatically set to On for the French locales and a few others. Users normally would
-not need to explicitly set this attribute. There is a string comparison performance cost when
-it is set On, but sort key length is unaffected.
-Example:
-F=X cote < cote < cote < cote
-F=O cote < cote < cote < cote
-
-CASE_FIRST - The Case_First attribute is used to control whether uppercase letters come before
-lowercase letters or vice versa, in the absence of other differences in the strings. The possible
-values are Uppercase_First (U) and Lowercase_First (L), plus the standard Default and Off.
-There is almost no difference between the Off and Lowercase_First options in terms of results,
-so typically users will not use Lowercase_First: only Off or Uppercase_First. (People interested
-in the detailed differences between X and L should consult the Collation Customization).
-Specifying either L or U won't affect string comparison performance, but will affect the sort key
-length.
-Example:
-C=X or C=L "china" < "China" < "denmark" <
-"Denmark"
-C=U "China" < "china" < "Denmark" < "denmark"
-
-CASE_LEVEL - The Case_Level attribute is used when ignoring accents but not case. In such a situation,
-set Strength to be Primary, and Case_Level to be On. In most locales, this setting is Off by default.
-There is a small string comparison performance and sort key impact if this attribute is set to be On.
-Example:
-S=1, E=X role = Role = role
-S=1, E=O role = role < Role
-
-NORMALIZATION_MODE - The Normalization setting determines whether text is thoroughly normalized
-or not in comparison. Even if the setting is off (which is the default for many locales), text as
-represented in common usage will compare correctly (for details, see UTN #5). Only if the accent
-marks are in noncanonical order will there be a problem. If the setting is On, then the best
-results are guaranteed for all possible text input. There is a medium string comparison performance
-cost if this attribute is On, depending on the frequency of sequences that require normalization.
-There is no significant effect on sort key length. If the input text is known to be in NFD or NFKD
-normalization forms, there is no need to enable this Normalization option.
-
-STRENGTH - see Collator::setStrength chapter.
-
-ALTERNATE_HANDLING - The Alternate attribute is used to control the handling of the socalled
-variable characters in the UCA: whitespace, punctuation and symbols. If Alternate is set to
-NonIgnorable (N), then differences among these characters are of the same importance as
-differences among letters. If Alternate is set to Shifted (S), then these characters are of only
-minor importance. The Shifted value is often used in combination with Strength set to Quaternary.
-In such a case, whitespace, punctuation, and symbols are considered when comparing strings,
-but only if all other aspects of the strings (base letters, accents, and case) are identical.
-If Alternate is not set to Shifted, then there is no difference between a Strength of 3 and
-a Strength of 4. For more information and examples, see
-Variable_Weighting in the UCA (http://www.unicode.org/reports/tr10/#Variable_Weighting).
-The reason the Alternate values are not simply On and Off is that additional Alternate values
-may be added in the future. The UCA option Blanked is expressed with Strength set to 3,
-and Alternate set to Shifted. The default for most locales is NonIgnorable. If Shifted is selected,
-it may be slower if there are many strings that are the same except for punctuation;
-sort key length will not be affected unless the strength level is also increased.
-Example:
-S=3, A=N di Silva < Di Silva < diSilva < U.S.A. < USA
-S=3, A=S di Silva = diSilva < Di Silva < U.S.A. = USA
-S=4, A=S di Silva < diSilva < Di Silva < U.S.A. < USA
-
-HIRAGANA_QUATERNARY_MODE - Compatibility with JIS x 4061 requires the introduction of an additional
-level to distinguish Hiragana and Katakana characters. If compatibility with that standard is required,
-then this attribute should be set On, and the strength set to Quaternary. This will affect sort key
-length and string comparison string comparison performance.
-
-NUMERIC_COLLATION - When turned on, this attribute generates a collation key for the
-numeric value of substrings of digits. This is a way to get '100' to sort AFTER '2'.

-/**
- * Number formatter class - locale-dependent number formatting/parsing.
- *
- * This class represents the ICU number formatting functionality. It allows to display
- * number according to the localized format or given pattern or set of rules, and to
- * parse strings into numbers according to the above patterns.
- *
- * Example:
- * <code>
- * $value = 1234567;
- * $formatter = new NumberFormatter("de_DE", NumberFormatter::DECIMAL);
- * echo $formatter->format($value);
- * </code>
- *
- * @see http://www.icu-project.org/apiref/icu4c/unum_8h.html
- * @see http://www.icu-project.org/apiref/icu4c/classNumberFormat.html
- *
- * The class would also contain all the constants listed in the following enums:
- * UNumberFormatStyle, UNumberFormatRoundingMode, UNumberFormatPadPosition,
- * UNumberFormatAttribute, UNumberFormatTextAttribute, UNumberFormatSymbol.

-/**
- * A "Locale" is an identifier used to get language, culture, or regionally-specific 
- * behavior from an API. PHP locales are organized and identified the same
- * way that the CLDR locales used by ICU (and many vendors of Unix-like operating 
- * systems, the Mac, Java, and so forth) use. Locales are identified using
- * RFC 4646 language tags (which use hyphen, not underscore) in addition to the
- * more traditional underscore-using identifiers. Unless otherwise noted
- * the functions in this class are tolerant of both formats. 
- *
- * Examples of identifiers include:
- *
- *  * en-US (English, United States)
- *  * zh-Hant-TW (Chinese, Traditional Script, Taiwan)
- *  * fr-CA, fr-FR (French for Canada and France respectively) 
- *
- * The Locale class (and related procedural functions) are used to interact 
- * with locale identifiers--to verify that an ID is well-formed, valid, 
- * etc. The extensions used by CLDR in UAX #35 (and inherited by ICU) are 
- * valid and used wherever they would be in ICU normally.
- *
- * Locales cannot be instantiated as objects. All of the functions/methods 
- * provided are static.
- *
- *   * The null or empty string obtains the "root" locale. 
- *     The "root" locale is equivalent to "en_US_POSIX" in CLDR.
- *   * Language tags (and thus locale identifiers) are case insensitive. There
- *     exists a canonicalization function to make case match the specification.
- *
- * @see http://www.icu-project.org/apiref/icu4c/uloc_8h.html
