added HUC layer toggle, off by default
recoded, fixed some stuff, cleaned up.  toggle button changes text on click.  thanks Carl
Broken:  error layer.getVisibility

is not a function... but getVisibility is a method of the layer.  not
sure what the issue is.
Added self to developers list in pom
Added layer event handler for two point-based raster layers that have a click  to identify operation on them in order to fix an xy offset issue
