/**
 * Arguments parser, is cli and web agnostic.
 * @warning
 *   There are some quirks about the argument format:
 *     - Short flags cannot be chained together
 *     - Any number of hyphens are allowed to lead flags
 *     - Flag values cannot have spaces in them
 *     - You must specify an equal sign, --foo=value; --foo value doesn't work
 *     - Only strings and booleans are accepted
 *     - This --flag=off will be interpreted as true, use --flag=0 instead
 * @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.
 * @param $aliases
 *
