tamasmeszaros d4fe7b5a96 Adding rotating calipers algorithm for minimum are bounding box rotation.
Cleanup, fix build on windows and add test for rotcalipers.

Try to fix compilation on windows

With updates from libnest2d
Another build fix.


Clean up and add comments.


adding rotcalipers test  and some cleanup


Trying to fix on OSX


Fix rotcalipers array indexing


Get rid of boost convex hull.


Adding helper function 'remove_collinear_points'


Importing new libnest2d upgrades.


Disable using __int128 in NFP on OSX
