An object t of the class Tetrahedron_3 is an oriented tetrahedron in the three-dimensional Euclidean space $\E^3$.

It is defined by four vertices $p_0$, $p_1$, $p_2$ and $p_3$. The orientation of a tetrahedron is the orientation of its four vertices. That means it is positive when $p_3$ is on the positive side of the plane defined by $p_0$, $p_1$ and $p_2$.

The tetrahedron itself splits the space $\E^3$ in a positive and a negative side.

The boundary of a tetrahedron splits the space in two open regions, a bounded one and an unbounded one.
