PYTHON or JAVASCRIPT: get_ward function

[ssciere]

Dane has already written a working function but Windows users working on StreetWise can't run it locally since loading Geopandas is proving to be very challenging. I'm going to confirm that the function works on Heroku, in which case we can go ahead and use it. (We can probably just re-write the function to return n/a instead of crashing the program if geopandas can't be imported)

More to come!

The function Dane created works on Heroku! I added try/except so it won't throw an error in a local environment if the developer does not have geopandas.
