 * The EffectText Class allows one or more effects from the tweenMax library to be applied to individual letters in a block of text. These effects can be timed sequentially
 * The lineMetrics is taken care of for non-monotype fonts.
 * Alpha effects require the fonts to be embedded.
 * The text can have the ability to have rollover and rollout effects for use as links or menu items.
