Description:
------------
Sometimes it would be usefull to be able to define namespace relative to the current namespace content, for example in case of includes/requires where the same .skel is used over and over. See test script.

Test script:
---------------
// global file
namespace MyNS\Usr\Models
{
   require_once('MadMans\class.MadMansModel.php');
   
   print_r(
      new MadMan\MadMansModel()  /* which refers to MyNs\Usr\Models\MadMan\MadMansModel */
   );
}


// required file
namespace .\MadMan
{
   class MadMansModel
   {   // ..
   }
}
