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.

// Function: IdComponent::p_reference (protected)
// Purpose Creates a reference to an HDF5 object or a dataset region.
// Parameters
// name - IN: Name of the object to be referenced
// dataspace - IN: Dataspace with selection
// ref_type - IN: Type of reference; default to \c H5R_DATASET_REGION
// Return A reference
// Exception H5::IdComponentException
