/**
 * Click-tracking extension for Omniture tracking.
 *
 * Include this file on every page you would like to track specific clicks,
 * e.g. click on print buttons. Call function omni_clickTrack() in onclick-event
 * to activate tracking for specific click-events.
 *
 * Prerequisites
 * =============
 * 1.) Omniture sitecatalyst script must be included before using this function.
 *     This will be tested before function omniTrackClickEvent is defined.
 * 2.) Page tracking has to have taken place already (s-Object be initialised correctly)
 *     This will not be tested directly, though the existence of the s-object is tested.
 * 3.) s_account has to be set to active Omniture account
 *
 * Properties, that will be set
 * ============================
 * s.events    : given event (by function parameter, e.g. event25)
 *
 * Example for usage
 * =================
 * <a onclick="if (typeof omniTrackClickEvent == 'function') {omniTrackClickEvent('event25')};" ...>Click me</a>
 *
