NgZone class

Handles and observes the side-effects of executing callbacks in AngularDart.

Most applications will not need to access or use this class. It may be used in order to get hooks into the application lifecycle or for hiding asynchronous actions from AngularDart that occur frequently (such as mouse movement, or a polling timer) and have a costly impact on change detection.
