Potential issue with old heme cases #87

This issue was identified by Suzanne. Tracking it here so it isn't lost.

I found a few cases that look wrong to me.

SEER 1998 multiple primary rules for hematopoietic cancer from the SEER 1998 manual When 2 cases both have the same histology in (9835 or 9727 or 9754), the rules are returning multiple primary. Shouldn't these be the same primary since they are the same histology? My guess is these specific histologies aren't included in the table in the SEER manual so the algorithm is calling them multiple?

SEER 2001 multiple primary rules for hematopoietic cancer Case 1 9950, Case 2 9960. The rules returned multiple but per the heme table, I think this should be a single.
