In sbrn3/disscat: Calculates Distances Between Single Cell RNA Seq Categories

If you attempt to run the distances on groups split by a second factor you will get an error if you the split factors are not present in each group. One can imagine if your groups were treatment groups and split was by cell type. If your treatment groups did not contain all the cell types this will throw an error. This function will remove any factors of the split that are not present in all groups.
