	initialization ordering.

	  for several function calls to save huge amounts of time
	* components/PureCylindricalCoordinate.hpp: added to have functional
	  coordinate that always stays in polar coordinates, i.e. no trig.
	  Based on PureCylindricalPoint added to /spacegeom/SpacePoint.*
	* components/HelicalSurface.cpp: use new PureCylindricalCoordinate
	  instead of CartesianCoord to save lots of unnecessary trig calls
