[ka-Map-users] getting to list of layers

I'm working on providing a mechanism for making layers queryable or  
not queryable and for including/not including queryable layers in a  
given query but its not done yet.

For now, you can get a list of all the layers (which are actually  
groups unless you've changed things around) by calling

var oMap = myKaMap.getCurrentMap();
var aLayers = oMap.getLayers();
