Feret3d

Computes the feret diameter with its information (orientation and terminal points)

3D Feret diameter returning a data structure containing :

the Feret diameter lenght,
the coordinates of the extrema points
the orientation $(\theta, \phi)$ associated to the Feret diameter, where $\theta \in [0, 2 \pi]$ and $\phi \in [0, \pi]$ .
