1/* Usage:
2 *  jQuery.csv()(csvtext)  returns an array of arrays representing the CSV text.
3 *  jQuery.csv("\t")(tsvtext)  uses Tab as a delimiter (comma is the default)
4 *  jQuery.csv("\t", "'")(tsvtext) uses a single quote as the quote character instead of double quotes
5 *  jQuery.csv("\t", "'\"")(tsvtext) uses single & double quotes as the quote character
6 *  jQuery.csv(",", "", "\n")(tsvtext)  returns an array of arrays representing the CSV text.
