Geolocation.

Finally figured geolocation out; the map will now center on your GPS
location once you give it permission.

Unfortunately, this still will not allow python to calculate things from
your position.  Thus, you still enter your coordinates into the class to
calculate this in Python.   I don't see any other way to do this than to
code the distance function in Javascript, since Python cannot access the
long + lat variables.

To do: distance in JS, figure out how to parse JSON with JS, etc.
Essentially write this program entirely in a PHP document.
