Multiple Item Support. Cylinder as Item

[tempyzero]

Hey David, First of all thank you for a great implementation. I wonder how can I use cylinders along with the cubes as item to pack in the container ( Multiple Item support). I tried to tweak the algorithm but it's kinda hard as I was unable to understand the certain terminology you used (eg. hmx pz bfx) and others. Can you put a little light on it.

Desired Output

Thanks a lot.
