Honeycomb library (OpenSCAD)

I made a Honeycomb library in an attempt to create a strainer. I ended up using other strategy due to the ridiculously small particles I'm trying to filter.

The Honeycomb library turns out to be very nice, so I decided to upload it for other people to use.

NOTE: The library create a 2D shape that can be extruded. OpenSCAD give much better results when creating a difference in 2D before extruding then creating a difference on 3D shapes.
