previously examples like $http where broken because we would strip part of the
filename (http-hello.html -> http)
we really want to strip only the id suffix that we append to disambiguate
common filenames (like index.html) which appear in many examples.
we now have two types of namespaces:
- true namespace: angular.* - used for all global apis
- virtual namespace: ng.*, ngMock.*, ... - used for all DI modules
the virual namespaces have services under the second namespace level (e.g. ng.)
and filters and directives prefixed with filter: and directive: respectively
(e.g. ng.filter:orderBy, ng.directive:ngRepeat)
this simplifies urls and makes them a lot shorter while still avoiding name collisions
