OpenSCAD Parametric Comb with Minkowski Rounded Teeth

OpenSCAD Parametric Comb with Minkowski Rounded Teeth

I was not totally satified with the hard edges of the original design. I found the code very clean and readable already, and added a new mode which is very processing intensive - so I have my doubts that the cloud based customizer will not time out...
Even if you customize the SCAD on your own machine if profile = "rounded" then you will have to anticipate a few minutes (~10) of calculation... Actually it seems to be a question of main memory availability whether the computer will be able to calculate the result. As the file and segmentation quality is adjusted my computer with only 4GB of RAM barely manages to render V4... (V5 took more than half an hour now)

Summary of additional changes:
- added an optional cleanupSaver bar that prevents bed adhesion _brim_ to extend between the teeth
- added a gap min variable so teeth get wider close to the comb body

I have now tested the print, and the cleanup saver works great! Th
