/*
================================================================================

Optimizations:

    1. Optimized legal().
    2. Implmented "char*" version of operator=().
    3. Added conditional inlining (for Pegaus internal use).
    4. Added comparison functions for "char*".
    5. Implemented "unchecked" version of constructors and assignment operators
       that take String or "char*".
    6. Added loop unrolling to CIMName::legal()
