-/// \brief A class that does preorder depth-first traversal on the
-/// entire Clang AST and visits each node.
-///
-/// This class performs three distinct tasks:
-/// 1. traverse the AST (i.e. go to each node);
-/// 2. at a given node, walk up the class hierarchy, starting from
-/// the node's dynamic type, until the top-most class (e.g. Stmt,
-/// Decl, or Type) is reached.
-/// 3. given a (node, class) combination, where 'class' is some base
-/// class of the dynamic type of 'node', call a user-overridable
-/// function to actually visit the node.
-///
-/// These tasks are done by three groups of methods, respectively:
-/// 1. TraverseDecl(Decl *x) does task #1. It is the entry point
-/// for traversing an AST rooted at x. This method simply
-/// dispatches (i.e. forwards) to TraverseFoo(Foo *x) where Foo
-/// is the dynamic type of *x, which calls WalkUpFromFoo(x) and
-/// then recursively visits the child nodes of x.
-/// TraverseStmt(Stmt *x) and TraverseType(QualType x) work
-/// similarly.
-/// 2. WalkUpFromFoo(Foo *x) does task #2. It does not try to visit
-/// any child node of x. Instead, it first calls WalkUpFromBar(x)
-/// where Bar is the direct parent class of Foo (unless Foo has
-/// no parent), and then calls VisitFoo(x) (see the next list item).
-/// 3. VisitFoo(Foo *x) does task #3.
-///
-/// These three method groups are tiered (Traverse* > WalkUpFrom* >
-/// Visit*). A method (e.g. Traverse*) may call methods from the same
-/// tier (e.g. other Traverse*) or one tier lower (e.g. WalkUpFrom*).
-/// It may not call methods from a higher tier.
-///
-/// Note that since WalkUpFromFoo() calls WalkUpFromBar() (where Bar
-/// is Foo's super class) before calling VisitFoo(), the result is
-/// that the Visit*() methods for a given node are called in the
-/// top-down order (e.g. for a node of type NamespaceDecl, the order will
-/// be VisitDecl(), VisitNamedDecl(), and then VisitNamespaceDecl()).
-///
-/// This scheme guarantees that all Visit*() calls for the same AST
-/// node are grouped together. In other words, Visit*() methods for
-/// different nodes are never interleaved.
-///
-/// Stmts are traversed internally using a data queue to avoid a stack overflow
-/// with hugely nested ASTs.
-///
-/// Clients of this visitor should subclass the visitor (providing
-/// themselves as the template argument, using the curiously recurring
-/// template pattern) and override any of the Traverse*, WalkUpFrom*,
-/// and Visit* methods for declarations, types, statements,
-/// expressions, or other AST nodes where the visitor should customize
-/// behavior. Most users only need to override Visit*. Advanced
-/// users may override Traverse* and WalkUpFrom* to implement custom
-/// traversal strategies. Returning false from one of these overridden
-/// functions will abort the entire traversal.
-///
-/// By default, this visitor tries to visit every part of the explicit
-/// source code exactly once. The default policy towards templates
-/// is to descend into the 'pattern' class or function body, not any
-/// explicit or implicit instantiations. Explicit specializations
-/// are still visited, and the patterns of partial specializations
-/// are visited separately. This behavior can be changed by
-/// overriding shouldVisitTemplateInstantiations() in the derived class
-/// to return true, in which case all known implicit and explicit
-/// instantiations will be visited at the same time as the pattern
-/// from which they were produced.
