Artillery_attitude_explained_charts_revised 1.02

Totally revised version of the Artillery Attitude Charts to replace the previous one.  This one revises the explanation and core concept to demonstrate on a compass what attitude in mils should be set depending on whether the desired artillery zone is wider than long, or vice versa, and how that corresponds with the axis of adjustment.  The emphasis is on a point in the center of the bombardment zone and how it aligns vs. 0 to 3200 mils, with 0 always oriented to the North. It also includes 2 examples.

Feedback/Improvement suggestions are welcome.
