CSV string parser

This function takes a comma separated string and parses the values into a variable-length array, which can then be assigned to a predefined number of variables, or iterated with a For-Next loop. This code is roughly based on Brant Gluth's submission entitled "Parse Delimited Text", with the addition of a demo form and improved string handling. Most noticeably, this code can handle strings enclosed in quotes and will not break on delimiter characters within the quotes.
