Elevation Ruler

This module allows the default Foundry measurement ruler to track change in elevation. Elevation can be changed while using the ruler in three ways:

1. Manually. Hit the specified hot key (default: '[' to increment and ']' to decrement).
2. Token. When hovering over a token with the ruler, the origin or destination elevation (as applicable) will update.
3. Enhanced Terrain Layer. If a terrain layer is present with a finite max elevation, that max elevation will be used for the elevation.

The distance calculation updates based on the distance measured, assuming a straight line in three dimensions between origin and destination, taking into account elevation change.

If you add a waypoint, elevation will be tracked at each waypoint.

If you choose to move the origin token (by hitting spacebar) after measuring, the token elevation will be updated along each waypoint.
