Plugin: Spherical Helix 1.0

This plugin draws a spherical helix (also known as a loxodrome, or a rhumb line).  It is a spiral curve on the surface of a sphere, which crosses all meridians of longitude at the same angle.

Conceptually, this is the path a ship would follow if it traveled around the earth without changing direction.  In other words, if the ship proceeded along a course with constant bearing relative to true north, then it would trace out a spherical helix (loxodrome) as it circled the globe.
