Hi List,

GGL contains circles and spheres, with (very few) functionality. Most 
functionality is for selecting objects within circles. Formally it is 
called "n-sphere", as the common term for 2D circles and 3D spheres and 
hyper-spheres.

For the review it is decided to move this to an extension, to not 
obfuscate the geometries with an outsider, and focus on a solid core.

So in case you use circles, then please extra include the headerfile 
<ggl/extensions/nsphere/nsphere.hpp>, with all functionality as it was.

Regards, Barend
