Typeahead is a AngularJS version of [Bootstrap v2's typeahead plugin](http://getbootstrap.com/2.3.2/javascript.html#typeahead).
This directive can be used to quickly create elegant typeaheads with any form text input.

It is very well integrated into AngularJS as it uses a subset of the
[select directive](http://docs.angularjs.org/api/ng.directive:select) syntax, which is very flexible. Supported expressions are:

* _label_ for _value_ in _sourceArray_
* _select_ as _label_ for _value_ in _sourceArray_

The `sourceArray` expression can use a special `$viewValue` variable that corresponds to the value entered inside the input.

This directive works with promises, meaning you can retrieve matches using the `$http` service with minimal effort.
