filletcube() OpenSCAD module

This a module for OpenSCAD to create a cube with rounded edges (fillets).

It doesn't use minkowski or hull, thus it renders fast (enought).

Usage:
Like the build in module cube(), the first parameter is an array [x,y,z]
The second, third, and fourth parameters are for the side, top and bottom fillet radius.
They can be adresses with side=, top= and bottom=. Theese parameters work with arrays and take four values.
Each value is the radius of the fillet on an edge, counted clockwise.
