/* JavaScript/ActionScript API
 * The JavaScript/ActionScript API facilitates interaction between the Flash movie and the web page in which it resides.
 *
 * The following functions can be invoked by the Flash movie:
 *
 * •	_ddTrack
 * •	_ddLink
 * •	_ddShowCard
 * •	_ddFindStore
 *
 * The Flash movie will use ActionScript’s ExternalInterface to interact with JavaScript on the containing page.
 * Note that the Flash embed must set  * allowScriptAccess to "always" for the JavaScript/ActionScript API to work.
 *
 * Function: _ddTrack
 * This function allows the Flash movie to fire tracking events. It then delegates to the Google Analytics _trackPageview() function.
 * Expects
 * PageLabel: a value that corresponds to the Google Analytics page label specified in the measurement plan for the event to be tracked.
 * Returns
 * Nothing.
 *
 * Function: _ ddLink
 * This function allows the Flash movie to direct the browser to another URL, optionally in a new window.
 * Expects
 * Url: the URL to which the browser window should open.
 * NewWindow: indicates whether a new browser window should be spawned.
 * Returns
 * Nothing.
 *
 * Function: _ ddShowCard
 * This function allows the Flash movie to display the E-card component.
 * This function will be patterned after the solution implemented for Bases Loaded: it will do some
 * JavaScript/div/iframe devilry (perhaps using ThickBox) to show the invite form/preview/confirm screens.
 * Expects
 * Nothing.
 * Returns
 * Nothing.
 *
 * Function: _ ddFindStore
 * This function allows the Flash movie to transfer control to the Store Locator on DunkinDonuts.com with a user-supplied ZIP code.
 * Expects
 * ZipCode: a five-digit USPS ZIP code
 * Returns
 * Nothing.
 *
