-parseCSV 0.2.0 beta
------------------------------------
-Date: 2-Jan-2007
-
-- Added auto() function to automatically detect
-  delimiter character.
-  Useful for user upload incase delimiter is
-  comma (,), tab, or semi-colon (;). Some
-  versions of MS Excel for Windows use
-  semi-colons instead of commas when saving to
-  CSV files.
-  It uses a process of elimination to eliminate
-  characters that can not be the delimiter,
-  so it should work on all CSV-structured files
-  almost no matter what the delimiter is.
-
-- Generally updated some of the core workings
-  to increase performance, and offer better 
-  support for large (1MB and up) files.
-
-- Added code examples to header comment.
