 /**
  * Creates a Hint object.
  * @class The Hint component allows you to create a rich tooltip to attach to an element.  You can customize
  * how long the mouse must remain on the element before showing the Hint, how long to wait before hiding the hint,
  * and what theme to apply to the Hint.
  * @constructor
  * @example
  * var hint = new nitobi.callout.Hint(1500, 1000, "clean");
  * hint.addHint("idOfElementToAttachTo", "Hint Title", "Hint Body");
  * @param {Number} [timerLength] How long to wait before showing the callout (on a mouseover).
  * @param {Number} [expireTimeout] How long to wait getting rid of the tooltip.
  * @param {String} [stylesheet] The callout stylesheet to use for the hints (XP by default).
