This new version brings few new meshing functions, and a big quality-of-life change regarding surface selections in meshes.

new features

added module madcad.hull and everything under it !
added generation.expand()
new Mesh inner identification system.

This feature concerns all data types in madcad.mesh and adds mainly the method .qualify() that helps labeling groups which helps selecting them afterward.

schemes displays are now highlighted when selected
functions generating finished parts are now returning a Solid ready for assembly
added support for partial kinematic joint definition in Solid.place()
