SearchController class

A controller to manage a search view created by SearchAnchor.

A SearchController is used to control a menu after it has been created, with methods such as openView and closeView. It can also control the text in the input field.

To observe open/close state changes of search view, provide SearchAnchor.viewOnOpen and/or SearchAnchor.viewOnClose callbacks.
