create_segment_association procedure performs SHM counts

Add a routine counting somatic hypermutations (SHM) to
the stored procedure generating the derived_segment_association
table. The routine only counts replacement mutations (both
synonymous and non-synonymous) and ignores insertions and
deletions as these typically rare and most likely sequencing
artifacts.
