*
* * __Angular expressions:__ Functions are bound to the Array objects and augment the Array type as
* array methods. The names of these methods are prefixed with $ character to minimize naming

*
* The following APIs are built-in to the angular Array object:
*
* * {@link angular.Array.add angular.Array.add()} - Optionally adds a new element to an array.
* * {@link angular.Array.count angular.Array.count()} - Determines the number of elements in an
* array.
* * {@link angular.Array.filter angular.Array.filter()} - Returns a subset of items as a new array.
* * {@link angular.Array.indexOf angular.Array.indexOf()} - Determines the index of an array value.
* * {@link angular.Array.limitTo angular.Array.limitTo()} - Creates a new array off the front or
* back of an existing array.
* * {@link angular.Array.orderBy angular.Array.orderBy()} - Orders array elements
* * {@link angular.Array.remove angular.Array.remove()} - Removes array elements
* * {@link angular.Array.sum angular.Array.sum()} - Sums the number elements in an array

*
* @param {Array} array The source array.
* @param {string|Object|function()} expression The predicate to be used for selecting items from
* `array`.
*
* Can be one of:
*
* - `string`: Predicate that results in a substring match using the value of `expression`
* string. All strings or objects with string properties in `array` that contain this string
* will be returned. The predicate can be negated by prefixing the string with `!`.
*
* - `Object`: A pattern object can be used to filter specific properties on objects contained
* by `array`. For example `{name:"M", phone:"1"}` predicate will return an array 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`: A predicate function can be used to write arbitrary filters. The function is
* called for each element of `array`. The final result is an array of those elements that
* the predicate returned true for.

* `add` is a function similar to JavaScript's `Array#push` method, in that it appends a new
* element to an array. The difference is that the value being added is optional and defaults to
* an empty object.
*
* Note: this function is used to augment the `Array` type in angular expressions. See
* {@link angular.Array} for more info.
*
* @param {Array} array The array expand.
* @param {*=} [value={}] The value to be added.
* @returns {Array} The expanded array.
*
* @TODO simplify the example.
*
* @example
* This example shows how an initially empty array can be filled with objects created from user
* input via the `$add` method.
