Add pan and associated files.  This is a lightweight test harness.  It works a
lot like runtests.py did, but it is more powerful.  See the man page for
details.

 * This is a heavily modified version of USC_parse_arg
 *
 * Synopsis
 *
 * char **splitstr(char *str, int *argcount, char *separator)
 *
 * Description
 * This function splits a string (str) into components that are separated by
 * one or more of the characters in the (separator) string.  An array of
 * strings is returned, along with argcount being set to the number of strings
 * found.
 *
 * To rid yourself of the memory allocated for the string:
 *	free( SplitstrReturn[0] );
 *	free( SplitstrReturn );
 *
