TypeError: Decimal('37.351158') is not JSON serializable

While working on Issue #6 , got this error at the route for JSON file of user's restaurant visits

Need to see how to pass the latitude and longitude that are Decimal types, which is not accepted by JSON

[itsahsiao]

Could convert latitude and longitude to strings/floats, which works:

"latitude": float(visit.restaurant.latitude),
"longitude": float(visit.restaurant.longitude)

But read that converting to floats could have rounding issues. Did not see any issues when I converted these two to floats, but saw solutions suggesting simplejson, which has support for Decimal type

Used simplejson as json

[itsahsiao]

When creating javascript function (for loop) to access each of user's visited restaurants and plotting markers, got this error in the browser console:

InvalidValueError: setPosition: not a LatLng or LatLngLiteral: in property lat: not a number

Per solution (http://stackoverflow.com/questions/20585055/uncaught-invalidvalueerror-setposition-not-a-latlng-or-latlngliteral-in-prope), numbers are not being passed in for latitude and longitude.

Decided to not use simplejson and just convert the latitude and longitude to floats in server.py, which fixed the error and markers now being plotted!
