[MONDRIAN-1933] [MONDRAIN-1934] improvements for native evaluation for
performance against large dimensions in specific usecases.  Added the
ability to natively evaluate subsets, and converted the subset function to
streaming.  Added the ability to natively evaluate filters utilizing the
count() method for filtering.  Also includes the ability to handle
AddCalculatedMembers() in filters as long as there are no calculated
members in the utilized dimension.  Also added a testing java servlet
filter for logging times spent in various filters.
