* Activate/Deactivate with a function call to grayOut(vis, options). “vis” is a true/false variable. 
* If you pass true, the screen will be grayed out. If you pass false, the gray-out will be removed. 
* “options” is an optional JSON object this allows you to send only the properties you want modified. 
* You don't have to pass options if you don't want. grayOut(true) and grayOut(false) will work quite 
* nicely. The three properties looked for in options are zindex, opacity, and bgcolor. 
*
* By default the gray-out creates a layer with a z-index of 50 and you will need to create or raise 
* elements's z-indexes to be higher than 50 to appear on top of the gray-out. If you need to, however, 
* you can set an option of {'zindex':'50'} where “50” is is changed to the z-index you wish to use.
