/*******************
* Letyn's comments 21.2.2007
* 1) It is necessary to put somewhere in the HTML page - eg: <div id="dhtmltooltip"></div>
* 2) Set style for tooltip eg:
*   #dhtmltooltip{
*    position: absolute;
*    width: 150px;
*    border: 2px solid black;
*    padding: 2px;
*    background-color: lightyellow;
*    visibility: hidden;
*    z-index: 100;
*  }
* 3) Use tooltip in the page eg: 
* <DIV onMouseover="ddrivetip('This DIV \'<br />has a tip!', '#EFEFEF')" onMouseout="hideddrivetip()">Some text here. Some text here.</div>
* 
* Note ddrivetip(thetext, thecolor, thewidth) has to optional parameters (color and width of the object)
