/* *parse*

   Input: A pointer to a two-dimensional character array, "output"

   Description: Parses the characters in "input" by the delimeter, modifies output, filling it with
                the strings resulting from the parse.

   Ouput: An int, indicating whether any instances of the delimeter were found in "input"
