Currently pylint test is not passing

This package is pretty similar to shapely.

An idea of optional configuration would be add support for this library, more specifically to convert shapely.Polygon into a shape

pip install compmec-shape[shapely]

The operation XOR between to circles does not give the correct result:

from compmec.shape import Primitive

circle_left = Primitive.circle(radius = 50, center = (-15, 0))
circle_right = Primitive.circle(radius = 50, center = (15, 0))
circle_xor = circle_left ^ circle_right 

Although using this operation we get the correct shape

circle_or = circle_left | circle_right
circle_and = circle_left & circle_right
circle_xor = circle_or - circle_and

The current implementation of __xor__ is theorically correct:

def __xor__(self, other):
    return (self - other) | (other - self)

We can create shapes by operating primitive shapes or by creating simple shapes, but it would be nice to have functions to import and export these shapes from a file

Currently the boolean operation between two shapes is made by FollowPath, which is inside the file shape.py.
The proposition is to move this responsibility to a new file called bool.py.

The main problem is: these functions receives BaseShape entities, Therefore we would have a circular import.
They are used to know if the midpoint of a segment is inside/outside the other shape.

A solution is to create a JordansContainer, like a tuple(tuple(JordanCurve)), that is used as input/output for a boolean operation.
