* 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 );
*
