Import CSV into DataSet

***UPDATED*** Import a CSV file into a dynamically created table in a Dataset. You can specify the field separator and text qualifier characters. You can say whether or not the first line in the CSV is the data header. You can save the imported CSV back out as CSV or XML. I use regular expressions to separate the fields, unlike some that use the Split function. Feel free to use and play with. If you find any problems, please let me know. The code has now been updated with the optional parameters removed turned into an overloaded procedure.
