[ka-Map-users] Turning off the scalebar

I have tried hiding the scalebar div (div id="scaleReference" and its 
children), which does remove the scalebar, but for reasons unknown also 
kills the legend - it shows up as a blank gray box.

Anyway, my suggestion was actually to have the ability in the ka-Map 
core to turn off the scalebar and/or legend for individual maps, 
probably with a new element in the $aszMapFiles array. This would 
essentially replicate the map file SCALEBAR STATUS ON/OFF functionality.

I rather like the "sample interface" myself - it is a nice design - 
though I am modifying it. Actually, I am impressed with ka-Map overall!
