IdlingRegistry

Handles registering and unregistering of IdlingResources with Espresso from within your application code.

These resources are required by Espresso to provide synchronisation against your application code. All registered resources with this registry will be automatically synchronized against for each Espresso interaction.

This registry along with IdlingResource interface are bundled together in a small light weight module so that it can be pulled in as a dependency of the App under test with close to no overhead.
