 * Params must start with - or /, and after the first param is encountered everything after is assumed to be
 * a param or parameter value.
 *
 * Each array returned from this contains a parameter and optionally any parameter values. For example, if your
 * input is ["cmd1", "cmd2", "-param1", "param1Value", "-param2"], the returned value will be:
 * [ ["-param1", "param1Value"], ["-param2"] ]
