* @brief Couples an XdmfArray with HDF5 data stored in a DSM buffer.

* Serves as an interface between data stored in XdmfArrays and data
* stored in DSM buffers. When an Xdmf file is read from or written
* to a DSM buffer an XdmfHDF5ControllerDSM is attached to XdmfArrays.
* This allows data to be released from memory but still be accessible
