inputs/CVS/: Joined together taxonImportance and stemCount tables to create stemCount_, because stemCount actually stores stem abundance by size, rather than grouping stems by organism (http://vegbankdev.nceas.ucsb.edu/vegbank/views/dba_tabledescription_detail.jsp?view=detail&wparam=stemcount&entity=dba_tabledescription&where=where_tablename), and is thus an AggregateOccurrence-related table along with taxonImportance
