The great arc interpolator computes interpolated positions along a great arc. A great arc is the shortest path between two positions on an ellipsoid.

CentralBody	Gets or sets the central body used when interpolating with Interpolate.
Granularity	Gets or sets the granularity, in radians, used when interpolating with Interpolate. Lower granularities are more precise but create more positions.
