Binh-Minh Ribler f5492ae03b [svn-r8593] Purpose:
Add more C++ wrapper and documentation - incrementally check-in

Description
    Added another overloaded constructor to StrType.
    Added doxygen documentation to H5IdComponent.cpp.
    Corrected some comments.

    This is an incremental check-in to preserve the code, corresponding
    tests will follow in a few weeks.

Platforms:
    SunOS 5.7 (arabica)
    Linux 2.4 (eirene)

Misc. update:
