In a nutshell, ETRACKBASE allows you to do the following: * * - Instantiate multiple instances of the class to implement different tracking contexts on a page. * - Define a tid attribute in the DOM element you want to track. * - Define optional pre-track and post-track JavaScript functions to be run before and after the tracking URI is fired respectively. * - Process static links with tid attribute and handle them using an implementation-specific function * * @example * Example 1: * Sending EDW data through 1x1 pixel * * Example 2: * Sending EDW data through script that returns 204 status * * Example 3: * Sending EDW data using both 1x1 and 204 script * * @constructor Instantiates a new tracking object that collects environment data (i.e. broswer info) automatically * and recieves key/value pairs from the controller logic through publically available method set(). * * @param string track_url The transport mechanism through which data is sent to the server.
