[svn-r8588] Purpose:

Browse Source 
Add C++ wrappers - incrementally check-in

Description
    Added wrapper for these C APIs:
        H5Rcreate
        H5Rget_obj_type
        H5Rget_region

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

Platforms:
    Linux 2.4 (eirene)
    I'm checking the code out and test on arabica too.
