Searching for Regions

By using the above Region Boundaries and labels you can plot the area covered and name quickly and easily WITHOUT plotting the data itself.  Then Enable and Disable those you wish to use as necessary.  These datasets are quite large and can be very slow to plot because they have not been optimized for TheSky as of yet!
