/**
* Call this method to enable/disable various debug runtime information in the compiler such as adding binding information
* and a reference to the current scope on to DOM elements. If enabled, the compiler will add the following to DOM elements
* that have been bound to the scope:
* - ng-binding CSS class
* - ng-scope and ng-isolated-scope CSS classes
* - $binding data property containing an array of the binding expressions
* - Data properties used by the scope()/isolateScope() methods to return the element's scope.
* - Placeholder comments will contain information about what directive and binding caused the placeholder. E.g. <!-- ngIf: shouldShow() -->.
*
* You may want to disable this in production for a significant performance boost.
* @see
https://docs.angularjs.org/guide/production#disabling-debug-data */
