Although Baby3D aims to keep things simple I thought it could come in handy to have at least one other primitive. So this update adds the Cylinder behavior which unsurprisingly lets you create cylinder shaped meshes. 

The most unique thing about this behavior is that the cylinder can have different diameters on top and bottom. You control this with the width(bottom) and height(top) of the object. For an even cylinder have width and height be the same.

Changelog is not really necessary this time, it's just the new behavior. Until next update...
