Adjacency Matrix Upload

There should be n + 1 rows and n + 1 columns (one for each item plus a column and row of labels).  Nodes will be connected to each other with edge weight e equal to the corresponding entry in the adjacency matrix.  Edge weights less than the input relevance threshold are removed.
