Description:

Similar to the csv match functions. Takes delimited data and returns entire rows where match column holds matchvalue, again with option to get all or get rows not matching. Performance seems to be OK for row counts in the low thousands.
v 1.02 1/27/2011
Added option to handle matchValue as list
