First draft of a color scalebar that queries ncWMS for the image and bounds and draws an element on the map
Second revision of the color scalebar control for the pdp raster portal:
+ Modified it to use pdp_util.raster.RasterMetadata app instead of ncWMS
+ hooked up the layer event handler to refresh the scale bar with the layer changes
+ added the div to the main map template
+ initialized the control on the bc_prism map
Fixed the styling to not show the element border unless the control has been initialized
Changed the colorbar control's metadata URL to be relative to the present page (such that it will work for all pdp pages)
Enabled check for log scale when computing the scale's midpoint
Added raster metadata apps to the vic_gen1, bccaq_extremes, and bcsd_downscale apps as well as enabling the colorbar in their *_map.js files
Merge branch 'feature/2.2.0-dev_color_scalebar' into cleanup
Added EnsembleMemberLister subclasses to portal specific modules
Added a variable names map to the PRISM controls js page
