* This class was created to hold test cases for the parseCVS method extracted from DateUtilsTest in commons-lang.
* The code was originally submitted by Serge Knystautas sergek@lokitech.com. It was never
* fully implemented, and has been moved to the sandbox for further development. Recent discussion
* from the commons-dev mailing list:
* http://marc.theaimsgroup.com/?l=jakarta-commons-dev&m=108904098032038&w=2
* Moving the code to the sandbox satisfies bug is a temporary solution to
* http://issues.apache.org/bugzilla/show_bug.cgi?id=22172 but this issue needs to be considered
* when the class/method is further developed.
