Added multiset_partitions_baseline() - a (simplified) version of smichr's set-partition-based multiset partitions code for use as a sanity test and comparison.
Added multiset_partitions_baseline() - a (simplified) version of
smichr's set-partition-based multiset partitions code for use as a
sanity test and comparison.

Added a test using this baseline version.

Added a larger test case to the subrange test - some of the code paths
are only exercised with large multisets.
