Browse Source 
Description:
    Added wrappers for H5Fget_info2, H5Inmembers, and H5Itype_exists

        // Gets general information about this file.
        void getFileInfo(H5F_info2_t& file_info) const;

        // Returns the number of members in a type.
        static hsize_t getNumMembers(H5I_type_t type);

        // Determines if an element type exists.
        static bool typeExists(H5I_type_t type);

Platforms tested:
    Linux/32 2.6 (jam)
    Linux/64 (jelly)
    Darwin (osx1010test)
