Created map.html, MapView, url, and updated base.html

I created a map.html, and use base to include the navbar.
I believe the urls are looking like thy should now, with the map url added.
I created a map view to load the map.html
Base.html was confusing to me, but I believe I have things worked out. Additions should work by following the "block" pattern laid out.
