Merging!

Thanks @amenadiel! This is a great addition! Very nice to be able to customize a new map without having to dive into maps_lib.js

Now it's as easy as:

          var myMap = new MapsLib({
            fusionTableId:      "1m4Ez9xyTGfY2CU6O-UgEcPzlS0rnzLU93e4Faa0",
            googleApiKey:       "AIzaSyA3FQFrNr5W2OEVmuENqhb2MBB2JabdaOY",
            locationColumn:     "geometry",
            map_center:         [41.8781136, -87.66677856445312],
            locationScope:      "chicago",
          });

@amenadiel also, you'll notice I deleted index_amd.html. It didn't seem distinct enough to warrant including. For those who like require.js, I'm ok with them figuring out how to use it themselves.

No problem. The example meant to justify the inclusion of the optional define call.
