geometry3d

Implemented classes of 3d objects:
* Vector
* Point
* Line
* Plane
* LineSegment

Yet incompletely implemented classes:
* Triangle
* Disk (closed circle)
* Union (a collection of 3d objects)

Each object has methods for finding its sizes, containing box or containing sphere. It finds intersection and distance or closest to another object part of itself. It also can tell if it contains the other object or is it contained by that. Where appropriate, it's easy to check orthogonality and parallelism.

Vectors are sub-typed from numpy ndarray class.

Extensive unit tests are included. Test coverage exceeds 95%.
