Option of specifying center

[lionelbrits]

First off, great library! Just wanted to say it would be a nice to be able to specify whether the produced object is to be centered, or not, as in the vanilla OpenSCAD primitives, by specifying center=true. Similiarly being able to specify diameter rather than radius, so that chamferCylinder can be used as a drop-in replacement for cylinder, etc.

While I agree that such option would be desired even just to conform with the native cube() interface, the author has already expressed this opinion in #4 and provided a workaround.
