Further integration for Vizier.

Further integration for Vizier.

Further integration of Vizier adjustable parameters,

This patch connects up additional configurable two pass rate control
parameters for the Vizier project.  This still needs to be connected up
to a command line interface and at the moment should still be using
default values that match previous behavior.

Do not submit until verified that defaults are all working correctly.
