/*-- Usage: 
     $cfg = new Config();
     $cfg->test = 'sweet';
     $cfg->test; (returns sweet)
     If the class can't be accessed as a global:
     Config::get('test') (returns sweet)
     
     You also can create more than one instance, however, that data is carried over.
     $config = new Config();
     $config->test (returns sweet)
