Another speed improvement to the interpolator function. This change fully vectorizes the interpolation: a DataFrame is created in which each column represents a unique_trip_id and the index is stop_sequence. Running DataFrame.interpolate() interpolates values on all trips at once, and the values are merged back.
I added a few unit tests for this function as well. @sablanchard it would be helpful to look over the return values to make sure they're behaving as intended.
