Config is a class method. That info is merged with config from the app (so 
your config file etc. data gets added) and the merged data is handed to the 
Controller's new().

 From within a View/Model/Controller you should *never* be calling 
$self->config; it won't contain data from ConfigLoader or the app config so 
it's liable to be wrong. Use the data in the object itself. I usually add an 
accessor every time I add a config key (via __PACKAGE__->mk_accessors) and 
then use that.
