Populate Node Position Label as appropriate

[Pilot-Marc]

Background

Populate the "Tap a node to see location" label

Breaking Changes

Added the .short property extension to Double, I suppose this could conflict with a pre-existing extension of the same name.

Details:

• The label is now populated as a result of a hit test match, with coords, elevation, and tag
• Changed hitTest to hitTests, because its an array
• Added left padding to the label to visually match the label below it (and because it's the right thing to do)
• Added The Alamo to the poi list, mostly because my office faces South and I was getting tired of continuously turning around to test the app

Meta

• Tied to Version Release(s):

Could we have degree symbols, and "m" for the altitude? I didn't understand what I was seeing at first, thought they might have been x/y/z world coordinates.

[Pilot-Marc]

Done. I thought about adding additional text such as full word "meters", or "N,E,S,W" for the coords, but skipped that to be respectful for narrow devices.

There's lots of good stuff at https://github.com/FormatterKit/FormatterKit for angles. Not an appropriate dependency for a library demo, but I use several of those formatters for production.
