Redo indexing for a LongTable object to remove any gaps in integer indexes

After subsetting a LongTable, it is possible that values of rowKey or colKey could no longer be present in the object. As a result there the indexes will no longer be contiguous integers. This method will calcualte a new set of rowKey and colKey values such that integer indexes are the smallest set of contiguous integers possible for the data.
