* This replaces the video stream methods for forcing adaptation with a mock resource that triggers overuse. * Resources can now be injected to the Module using the AddResource function. * Resources now have tests for adding and removing callbacks. * Quality/EncoderUse% resources are tracked in the Resource list of the adaptation module. * The adaptation module ties all resources to a reason to keep stats working as expected.
