Map Zoom Invert

Introduction
The Google Maps Android app contains a single-finger zoom gesture: double tap on the map, then slide your finger up or down to zoom. I find this gesture quite handy, so I was quite surprised when a Maps update that rolled out a few months ago inverted the gesture without warning. Now you swipe up to zoom out and down to zoom in. This behavior is frustrating to me not only because I'm used to the old behavior, but because it now behaves opposite of the desktop version of Maps! Scrolling up zooms in on the desktop, but swiping up zooms out on Android.

The Module
This module, once installed, will intercept the single-finger zoom gesture in Google Maps and invert it, restoring the old behavior: swipe up to zoom in, swipe down to zoom out.
