Description copied from class: ArgHandler

Attempts to process one flag or "extra" command-line argument (that appears without a flag).

Parameters:: args - the arguments passed in to main(); startIndex - an index into args indicating the first argument to use. If this is a handler for a flag argument. Otherwise it's the index of the "extra" argument.
Returns:: the number of additional arguments consumed, not including the flag or extra argument. Alternately, returns -1 if the argument cannot be used. This will causes the program to abort and usage to be displayed.
