/**
 * Arguments parser, is cli and web agnostic.

 *     - Short boolean flags cannot be chained together
 *     - Only strings, integers and booleans are accepted
 * @param $AC
 *   Arguments array to populate. This takes a simple format of 'argument'
 *   => default value. Depending on the type of the default value,
 *   arguments will be typecast accordingly. For example, if
 *   'flag' => false is passed, all arguments for that will be cast to
 *   boolean. Do *not* pass null, as it will not be recognized.
