Investigate computation of Strike and Dip in PlaneUtils

[Peter Powers]

Current implementations are cartesian; we need geographic equivalents.
Ensure consistent implementation of strike and dip calculations across project.

This ticket motivated by email exchange:

I assume this requires conversion to a cartesian coordinate system?

What would you recommend as the best way to do this?

use

static getStrikeAndDip(double[][] verticesIn)

I'm pretty sure it's written assuming depth is positive up so you'll probably have to change sign when pulling x,y,z vals from Locations.

Peter, still an open issue or punt to 1.4?
