definition of a polyhedral geometry in R^3 Generally, a polyhedron is a list of polygonal faces.

But data is storages differently to avoid pointer manipulation So, we decide to store:

the list of vertices -> Vector<Point> p_
the definition of faces as a list of points -> Vector<Vector<number_t> > faces_ it is so that p_[faces_[i][j]] is the j-st vertex of the i-st face of the polyhedron
the number of nodes on each edge -> Vector<Vector<number_t> > n_ it is so that n_[i][j] is the number of nodes on j-st edge [ p_[faces_[i][j]] p_[faces_[i][j+1]] ] of the i-st face of the polyhedron

Polyhedron constructors are based on a key-value system. Here are the available keys:

_faces: the geometrical faces defining the Polyhedron
_nnodes: to define the number of nodes on each edge of the Polyhedron
_hsteps: to define the local mesh steps on the vertices of the Polyhedron
_domain_name: to define the domain name
_side_names: to define the side names
_varnames: to define the variable names for print purpose
