Remove the concept of min/max zoom level from Map. Replace it with concept of num zoom levels. Bit of rearrangement in the initResolutions() function in HTTPRequest.js. Adapt all of OL to deal with numZoomLevels instead of min/max. Fix PanZoomBar so that it listens for change of baselayer and redraws itself. fix all tests so they pass. Add zoomLevels.html example for playing around with different methods of setting zoomlevels.
