// Purpose: You can use this function to gain access to the HTML element you want to influence.
//          It will pass you the HTML element you asked for, regardless of browser DOM. Of course,
//          the element must have a proper ID and, if your script must work in Netscape 4, should have a position defined in the style sheet.
// Returns: The object with properties 
//            .obj giving access to the actual HTML element. You have to use this property to read out or set anything else than styles. 
//            .style giving access to the styles of the HTML element. You have to use this property to read out or set the styles of the element. 
// Example: var x = new getObj('layername');
//
