Properties :
    * Made of a list of ND points
    * Made of a list of ND cells :
        * a 2D cell is made of a LuT of 3 points or more. All points must be coplanars.
        * a 3D cell is made of a LuT of 4 or more points.

* 2D cell example :

* 3D cell example :

Optionnal :
    * Can compute the energy for a cell from the points and their orders.
    * Can compute the normal (and triangle orientation, useful to orient resulting vectors in physical computation like collisions) from :
        * a given LuT
        * the given order of the points
    * Made of a LuT cell -> value
    * Made of a LuT edge -> value
    * Made of a LuT vertice -> value
    * Made of a dynamic rendering function which can deduce :
        * cell value from edges or/and vertices.
        * edges value from cell or/and vertices.
        * vertice value from cell or/and edges.

Must to have utilities :
    * Should be able to give the boudning box quickly.
    * An image of mesh shall be able to tell if it is convex or concave.
    * Detecting if a point is located within the mesh

Nice to have utilities :
    * For concave mesh : implement a quick convex decomposition of the mesh.
    * Remesh
    * Split by a plane
    * Merging two meshes
    * Hole detection
    * Detecting if a mesh colides another mesh
    * Uniformazing the mesh size
