[Nuno David Lopes <ndl@xxxxxxxxxxxxxx>]

There goes:
Rectangle, (copy/paste, with added parameters, of the UnitSquare case)
Box (copy/paste, with added parameters, of the UnitCube case)	
and UnitCircle.
(copy/paste, with added parameters and variable transformations, of the 
UnitSquare case)	
I've included a sandbox/built-in_mesh/
for testing the Circle case.
I will include the Cylinder and Sphere case only if you think that 
the UnitCircle is of any use, since they use the same transformations .

Thanks.
