* Partitions an XdmfGrid into a number of partitions using the metis library. Currently supported topology types are:
*
* XDMF_TRI, XDMF_TRI_6, XDMF_QUAD, XDMF_QUAD_8, XDMF_TET, XDMF_TET_10, XDMF_HEX, XDMF_HEX_20, XDMF_HEX_24, XDMF_HEX_27
*
* The routine splits the XdmfGrid and also splits all attributes and sets into their proper partitions. An attribute named
* "GlobalNodeId" is added that serves to map child node ids to their global id for the entire spatial collection.
*
* @param grid a XdmfGrid* to partition
* @param numPartitions the number of partitions to split the grid into
* @param parentElement the parent XdmfElement* to insert the created spatial collection of partitioned grids.
*
* @return XdmfGrid* a spatial collection containing partitioned grids.
