// Version from 08.04.2006

// xxxxxxxxxxx there is only this one public function, which you call from your html to show/hide a layer with a transition
// 1. parameter: <layerName>		=> layer name
// 3. parameter: <timeInMilliSec>	=> duration in milliseconds
// 4. paraneter: <transition>		=> transition type (string)
//										values: 'zoom', 'wipeRight', 'wipeLeft', 'wipeUp', 'wipeDown', 'pushRight', 'pushLeft', 'pushUp', 'pushDown'
// 5. parameter: <easeFunctionShow>	=> which tween ease function to apply for the "show" transition => must be a function which returns a value between 0.0 and 1.0
// 6. parameter: <easeFunctionHide>	=> which tween ease function to apply for the "hide" transition => must be a function which returns a value between 0.0 and 1.0

// example: <a href="javascript:transLayer('Layer1', 1000, 'zoom', 0, EaseTweens.EaseOut, EaseTweens.EaseIn)">zoom</a>
// zoom Layer1 in over a period of 1 second, use EaseOut for the "show" transition and Ease)
