// COMMENTS:
//
//  We may end up templating later if this works, but we'll probably do a major rewrite
//  in that case anyway.  Instead, we will define two basic types:
//
//  dataType:   the underlying type of the data being processed
//  indexType:    the type required for indices - should normally be signed, so we can
//          use negative deltas in a couple of places
//
//  Part of the reason for this is that we expect to migrate to 64-bit indices later
//  and it would be awkward to have to go back and rewrite
