Basically I have a table (csv - table 1) of data for a set of samples (rows), and a second table (table 2) of information about a subset of samples of particular interest.  I want to pull out the data from table 1 for the samples in table 2, either by:
> *	Merging the two tables based on a common identifier (SampleID - may have a different header in the two tables), and filter for overlapping entries (preferred approach)
> *	OR filter table 1 for entries where SampleID matches to one in a list taken from table 2
