+Return the application level configuration (which is not yet merged with any

+In this case $config is the hashref C< {a=>1, b=>2} >.

+existing L<Catalyst> standards for where a plugin should put its configuration.

+
+A Hashref of L<Catalyst::Component> subclasses that are 'injected' into configuration.
+For example:
+
+ MyApp->config({
+ inject_components => {
+ 'Controller::Err' => { from_component => 'Local::Controller::Errors' },
+ 'Model::Zoo' => { from_component => 'Local::Model::Foo' },

+ 'Model::Zoo' => { a => 2 },
+ 'Model::Foo' => { a => 100 },
+ });
+
+Generally L<Catalyst> looks for components in your Model/View or Controller directories.
+However for cases when you which to use an existing component and you don't need any
+customization (where for when you can apply a role to customize it) you may inject those
+components into your application. Please note any configuration should be done 'in the
+normal way', with a key under configuration named after the component affix, as in the
+above example.
+
+Using this type of injection allows you to construct significant amounts of your application
+with only configuration!. This may or may not lead to increased code understanding.
+
+Please not you may also call the ->inject_components application method as well, although
+you must do so BEFORE setup.
