Finalize tests/methods for basic Geometry library

[tvoinarovskyi]

Review and cleanup for: Vector

• [ ] Probably change name to something like Vec2, as it's 2D
• [ ] Method definitions (cross, normalize, rotate_deg?...)
• [ ] Vector test coverage

Lines

• [ ] Write Line, Ray and Segment classes. Simple method definitions, no need for BaseShape implementation, as it is not one. Class mostly for graphical representation to be easily mapped (like in Scene or Debug Drawer)
• [ ] Test coverage

Shape base Geometry methods

• [ ] Translate
• [ ] Arbitrary Affine transformations
• [ ] Calculate AABB

AABB specific methods Those are needed for Bounding Volume properties of the AABB

• [ ] Union
• [ ] Intersection
• [ ] Area
