 * the 5 array elements described in detail below:
 * 
 *
 * <dl>
 * <dt>contextElementOrId &#60;String|HTMLElement&#62;</dt>
 * <dd>A reference to the context element to which the overlay should be aligned (or it's id).</dd>
 * <dt>overlayCorner &#60;String&#62;</dt>
 * <dd>The corner of the overlay which is to be used for alignment. This corner will be aligned to the
 * corner of the context element defined by the "contextCorner" entry which follows. Supported string values are:
 * "tr" (top right), "tl" (top left), "br" (bottom right), or "bl" (bottom left).</dd>
 * <dt>contextCorner &#60;String&#62;</dt>
 * <dd>The corner of the context element which is to be used for alignment. Supported string values are the same ones listed for the "overlayCorner" entry above.</dd>
 * <dt>arrayOfTriggerEvents (optional) &#60;Array[String|CustomEvent]&#62;</dt>
 * <dd>
 * 
 * By default, context alignment is a one time operation, aligning the Overlay to the context element when context configuration property is set, or when the <a href="#method_align">align</a>
 * method is invoked. However, you can use the optional "arrayOfTriggerEvents" entry to define the list of events which should force the overlay to re-align itself with the context element.
 * This is useful in situations where the layout of the document may change, resulting in the context element's position being modified.
 * 
 * 
 * The array can contain either event type strings for events the instance publishes (e.g. "beforeShow") or CustomEvent instances. Additionally the following
 * 3 static container event types are also currently supported : <code>"windowResize", "windowScroll", "textResize"</code> (defined in <a href="#property__TRIGGER_MAP">_TRIGGER_MAP</a> private property).
 * 
 * </dd>
 * <dt>xyOffset &#60;Number[]&#62;</dt>
 * <dd>
 * A 2 element Array specifying the X and Y pixel amounts by which the Overlay should be offset from the aligned corner. e.g. [5,0] offsets the Overlay 5 pixels to the left, after aligning the given context corners.
 * NOTE: If using this property and no triggers need to be defined, the arrayOfTriggerEvents property should be set to null to maintain correct array positions for the arguments.
 * </dd>
 * </dl>
 *
 * 
 * For example, setting this property to <code>["img1", "tl", "bl"]</code> will
 * align the Overlay's top left corner to the bottom left corner of the
 * context element with id "img1".
 * 
 * 
 * Setting this property to <code>["img1", "tl", "bl", null, [0,5]</code> will
 * align the Overlay's top left corner to the bottom left corner of the
 * context element with id "img1", and then offset it by 5 pixels on the Y axis (providing a 5 pixel gap between the bottom of the context element and top of the overlay).
 * 
 * 
 * Adding the optional trigger values: <code>["img1", "tl", "bl", ["beforeShow", "windowResize"], [0,5]]</code>,
 * will re-align the overlay position, whenever the "beforeShow" or "windowResize" events are fired.
