This version adds support for reordering sparse matrices by first partitioning the adjacency graph using METIS and then grouping rows and columns by the parts that were assigned by the partitioner.

This version fixes an issue with the METIS partitioning and nested dissection reordering of non-square matrices. The fix ensures that the data structure representing the (undirected) bipartite graph of the matrix rows and columns is correctly passed to METIS.
