Purpose: Add new C++ wrappers
Description: Added wrappers for H5Pset_file_space and H5Pget_file_space // Sets the strategy and the threshold value that the library will // will employ in managing file space. void setFileSpace(H5F_file_space_type_t strategy, hsize_t threshold) const; // Returns the strategy that the library uses in managing file space. H5F_file_space_type_t getFileSpaceStrategy() const; // Returns the threshold value that the library uses in tracking free // space sections. hsize_t getFileSpaceThreshold() const; Platforms tested: Linux/32 2.6 (jam) Linux/64 (jelly) Darwin (osx1010test)
