/**
* We're trying to clean the REQUEST_URI in order to deduce the
* controller to load, method of the controller to call, and what
* arguments to send that method.
*
* For example:
* http://www.example.com/users/modify/83?profile=2
*
* Where:
* http://www.example.com/ -- root url as specified in $global['url']
* users -- is the controller we should instantiate and load
* modify -- method of the controller we should call
* 83 -- single argument to send to the modify method, but
* there could easily be more than one argument
* separated by additional /'s
* ? -- indicating the beginning of the query string
* and also the start of things we don't care about
* here
*
* Effectively:
* $obj = new Users();
* $obj->modify(83);
*
* Defaults:
* If no controller is provided, we default to $global['default_controller'] and
* if no method is provided, we default to $global['default_method']
