AutoComplete Control: Basic Local Data

This AutoComplete implementation points to a JavaScript array that is available in-memory, allowing for a zippy user interaction without the need for a server-side component. Enabling the prehighlightClassName and useShadow features, as well as pulling in the Animation utility, provides an ehanced visual user experience.

Implementers who are working with data from third-party sources, user input data, or otherwise untrustworthy sources should be sure to read the Security Considerations section of the AutoComplete user guide.
