-/**
- * Selects a subset of items from the provided [List] and returns it as a new
- * [List].
- *
- * In addition to the input list (implicit in an Angular expression syntax),
- * this filter takes 1 required and 1 optional parameter.  They are:
- *
- * - `expression` (required) - one of [Map], [Function], [String], [bool], [num]
- * - `comparator` (optional)
- *
- * <br>
- *
- * # expression
- *
- * can be one of:
- *
- * - [String], [bool] and [num]:  Only items in the List that directly
- * match this expression, items that are Maps with any value matching this
- * item and items that are Lists containing a matching items are returned.
- *
- * - [Map]:  This defines a pattern map.  Filters specific properties on objects
- * contained in the input List.  For example `{name:"M", phone:"1"}` predicate
- * will return a list of items which have property `name` containing "M" and
- * property `phone` containing "1".  A special property name, `$`, can be used
- * (as in `{$: "text"}`) to accept a match against any property of the object.
- * That's equivalent to the simple substring match with a `String` as
- * described above.
- *
- * - [Function]:  This allows you to supply a custom function to filter the
- * List.  The function is called for each element of the List.  The returned
- * List contains exactly those elements for which this function returned
- * `true`.
- *
- * <br>
- *
- * # comparator
- *
- * can be one of:
- *
- * - `bool comparator(expected, actual)`:  The function will be called with the
- * object value and the predicate value to compare and should return true if
- * the item should be included in filtered result.
- *
- * - `true`:  Specifies that only identical objects matching the expression
- * exactly should be considered matches.  Two strings are considered identical
- * if they are equal.  Two numbers are considered identical if they are either
- * equal or both are `NaN`.  All other objects are identical iff
- * identical(expected, actual) is true.
- *
- * - `false|null`:  Specifies case insensitive substring matching.
- *
- * <br>
- *
- * # Example ([view in plunker](http://plnkr.co/edit/6Mxz6r?p=info)):
- *
- * // main.dart
- * import 'package:angular/angular.dart';
- *
- * @NgDirective(selector: '[toy-data]')
- * class ToyData {
- * ToyData(Scope scope) {
- * scope.friends = [{'name':'John', 'phone':'555-1276'},
- * {'name':'Mary', 'phone':'800-BIG-MARY'},
- * {'name':'Mike', 'phone':'555-4321'},
- * {'name':'Adam', 'phone':'555-5678'},
- * {'name':'Julie', 'phone':'555-8765'},
- * {'name':'Juliette', 'phone':'555-5678'}];
- * }
- * }
- *
- * main() {
- * ngBootstrap([new AngularModule()..type(ToyData)], 'html');
- * }
- *
- * and
- *
- * <!-- index.html -->
- * <html>
- * <head>
- * <script src="packages/browser/dart.js"></script>
- * <script src="main.dart" type="application/dart"></script>
- * </head>
- * <body toy-data>
- * Search: <input type="text" ng-model="searchText">
- * <table id="searchTextResults">
- * <tr><th>Name</th><th>Phone</th></tr>
- * <tr ng-repeat="friend in friends | filter:searchText">
- * <td>{{friend.name}}</td>
- * <td>{{friend.phone}}</td>
- * </tr>
- * </table>
- * <hr>
- * Any: <input type="text" ng-model="search.$"> <br>
- * Name only <input type="text" ng-model="search.name"><br>
- * Phone only <input type="text" ng-model="search.phone"><br>
