Description

The PrimeMeridian class represents the line of longitude that is designated as 0 degrees.  All other lines of longitude are expressed by the angle by which they deviate from the PrimeMeridian.  Together with the equator of an Ellipsoid, the PrimeMeridian defines the origin of a GeodeticCoordSys.  In GeoCalc, a PrimeMeridian is defined by the angle that separates it from the Greenwich Meridian.
