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