 * Angular-Material-Mocks
 *
 * Developers interested in running their own custom unit tests WITH angular-material.js loaded...
 * must also include this *mocks* file. Similar to `angular-mocks.js`, `angular-material-mocks.js`
 * will override and disable specific Angular Material performance settings:
 *
 *  - Disabled Theme CSS rule generations
 *  - Forces $mdAria.expectWithText() to be synchronous
 *  - Mocks $$rAF.throttle()
 *  - Captures flush exceptions from $$rAF
