CAD-704: Create Box Zoom Functionality

[benrvars]

Release Notes and Issues

This creates the functionality for box zoom by using Google Maps drawing manager. It allows us to draw a rectangle, calculate the zoom, and propagate the change.

CAD-704

New Feature Testing Notes for QA:

• Select the magnifying glass button in the top right corner. When activated that button will change colors and the cursor on the map will be a cross.
• Once activated click, drag, and release or click, move mouse, and click again to draw a rectangle. The map will zoom to the rectangle as much as possible without cutting out anything enclosed by the drawn rectangle. You will also deactivate the box zoom mode.
• Once activated you can switch map modes and stay in box zoom. The color of the drawn rectangle should change.
• While activated if you select a category, manipulate the zoom/map with a scroll or the other zoom controls, or click the box zoom button again you will deactivate box zoom mode.

General notes

Front end

• I removed console references, window references, and general shenanigans
