 // Package gae provides a fakable wrapped interface for the appengine SDK's
 // APIs. This means that it's possible to mock all of the supported appengine
 // APIs for testing (or potentially implement a different backend for them).
 //
 // Features
 //
 // gae currently provides interfaces for:
 //   - Datastore
 //   - Memcache

 // and the state can be observed to see how many times each API was invoked.
 // Since filters stack, we can compare counts from rawCount versus userCount to
 // see how many calls to the actual real datastore went through, vs. how many
 // went to memcache, for example.
 //
 // Note that Filters apply only to the service.RawInterface. All implementations
 // of service.Interface boil down to calls to service.RawInterface methods, but
 // it's possible that bad calls to the service.Interface methods could return
 // an error before ever reaching the filters or service implementation.
