This maps uri's to controller modules as follows:

 /subdir/foo                    MyApp::C::Foo->default()

 /subdir/foo/bar                MyApp::C::Foo->bar()

 /subdir/foo/bar/zerm           MyApp::C::Foo->bar(), path_args == ['zerm']

 /subdir/foo/bar/biz            MyApp::C::Biz->default()

 /subdir/foo/biz/baz/noz/wiz    MyApp::C::Baz->noz(), path_args == ['wiz']

In the second example, if <MyApp::C::Foo> did not implement or allow <bar()> as a controller method, then this would select <MyApp::C::Foo-default()>>.

Implements find_controller() for Apache2::Controller::Dispatch with a simple hash-based mapping. Uses substr to divide the uri and exists to check cached mappings, so it should be pretty fast.

This dispatches URI's in a case-insensitive fashion.

Find the controller and method for a given URI from the data set in the dispatch class module.
