  Log:
  Many changes relating to conversion between cyclic and non-cyclic surface and curves.
  This is still broken, but I am pretty close to fixing it.
  The problem is that nurbana and blender make different assumptions about how
  a surface or curve should be stored in memory if it is cyclic:
  blender 	- stored identically to non-cyclic with extra knots
  		 	- automagically generate 'extra' loopy cyclic virtual CP
  
  nurbana 	- 'manually' converts a non-cyclic surface or curve
  			-	resulting surface/curve is also non-cyclic but appears to
  				be cyclic because extra virtual CP are copied to the end of the loop(s)
  
  All this means is that I have to manually convert to and from each style, and this
  is proving to be tricky because of (among other things) the fact that the CP are
  stored in a 1D array which needs to be resized and restored.
  
  This approach was adopted so as to preserve backwards compatibility. Converting
  nurbana to algorithmically deal with blender's cyclic style would be a large
  undertaking at this point.
  
  curve should still work fine. circle is temporarily broken, as is cyclic switching.
