 *  param is the input parameters. On exit param will point to the next parameter to parse. If the
 *      last paramter has been returned, param points to a null byte (*param = '0');
 *  target is the location to store any data aquired from the parameter. Caller is responsible to free this data.
 *  value is the string value of the parameter.
 *  command is any commands you need to run to help process the parameter's data.
