/*
* get_option_args
* This retrieves the desired option arguments from the OptionsARGV
* array. This is the function to use to retrieve options for any of
* the sub-algorithms (algorithms that are optional and not used
* generally).
* The options/arguments are accessed from the returned pointer.
* NOTE: there is no argument quoting yet. All arguments are
* whitespace delimited.
* To identify which algorithm a set of arguments belongs to the
* arguments need to be prefixed and postfixed with a key. For
* example (the colon is needed):
* OP Alt: arg0 arg1 arg2 arg3 :Alt
*
* NOTE: The key is case INsensitive. Also, if there is no
* terminating key the rest of the arguments are included in the
* returned argc.
* In the above example the returned value for argc would be 4 and
* the argv vector would start at arg0.
* WARNING: all of the following arguments after the key region are
* STILL accessible. Only the address of the first arg is set. No
* memory is duplicated.
* IMPORTANT NOTE: This does NOT follow the standard argc/argv
* conventions in main(). The argv[0] is the first ARGUMENT.
* Parameters:
* char *key: the key (case INsensitive)
* int *argc_ptr: a pointer to where to place argc.
* char ***argv_ptr: a pointer to where to place the argv address.
* (remember argv is accessed as an array of char
* ptrs. An array of char ptrs is of type char **.
* so this is just a pointer to the place to put
* the "array")
* Return Codes: returns TRUE if it can find the key region, FALSE
* otherwise
* Error Codes: See above and argc is set to -1 and argv is set to NULL
*
* Calling example:
* int argc;
* char **argv; -- this can NOT be an array
* int result;
*
* result = get_option_args("mykey", & argc, & argv); -- pass the addresses!
* if (result == TRUE) {
* printf("Got them\n");
* }
* else {
* printf("Could not find the args\n");
* -- error handling stuff here --
* }

* NOTE, get_token() is the function called to parse the tokens. If
* a parse is in progress just pass in NULL, this will get passed
* to get_token() the first time, retreiving the next token.
* Parameters:
* char *string: the string of tokens whitespace delimited
* Return codes: none
* Error codes: none
