/*************************************************************
* Window Onload Manager (WOM) v1.0
* Author: Justin Barlow - www.netlobo.com
*
* Description:
* The WOM library of functions allows you to easily call
* multiple javascript functions when your page loads.
*
* Usage:
* Add functions to WOM using the womAdd() function. Pass the
* name of your functions (with or without parameters) into
* womAdd(). Then call womOn() like this:
*     womAdd('hideDiv()');
*     womAdd('changeBg("menuopts","#CCCCCC")');
*     womOn();
* WOM will now run when your page loads and run all of the
* functions you have added using womAdd()
*************************************************************/
/*************************************************************
* The womOn() function will set the window.onload function to
* be womGo() which will run all of your window.onload
* functions.
*************************************************************/
function womOn(){
  window.onload = womGo;
}
/*************************************************************
* The womGo() function loops through the woms array and
* runs each function in the array.
*************************************************************/
function womGo(){
  for(var i = 0;i < woms.length;i++)
    eval(woms[i]);
}
/*************************************************************
* The womAdd() function will add another function to the woms
* array to be run when the page loads.
*************************************************************/
function womAdd(func){
	woms[woms.length] = func;
}
/*************************************************************
* The woms array holds all of the functions you wish to run
* when the page loads.
