GeFEM MesherObject object
This object represents a geometric object to be meshed by the
experimental meshing procedure of Getfem.
General constructor for MesherObject objects
 MF = MesherObject('ball', vec center, scalar radius)
Represents a ball of corresponding center and radius.
 MF = MesherObject('half space', vec origin, vec normal_vector)
Represents an half space delimited by the plane which contains the
origin and normal to normal_vector. The selected part is the part
in the direction of the normal vector. This allows to cut a geometry
with a plane for instance to build a polygon or a polyhedron.
 MF = MesherObject('cylinder', vec origin, vec n, scalar length, scalar radius)
Represents a cylinder (in any dimension) of a certain radius whose axis
is determined by the origin, a vector n and a certain length.
 MF = MesherObject('cone', vec origin, vec n, scalar length, scalar half_angle)
Represents a cone (in any dimension) of a certain halfangle (in radians)
whose axis is determined by the origin, a vector n and a certain length.
 MF = MesherObject('torus', scalar R, scalar r)
Represents a torus in 3d of axis along the z axis with a great radius
equal to R and small radius equal to r. For the moment, the
possibility to change the axis is not given.
 MF = MesherObject('rectangle', vec rmin, vec rmax)
Represents a rectangle (or parallelepiped in 3D) parallel to the axes.
 MF = MesherObject('intersect', MesherObject object1 , MesherObject object2, ...)
Intersection of several objects.
 MF = MesherObject('union', MesherObject object1 , MesherObject object2, ...)
Union of several objects.
 MF = MesherObject('set minus', MesherObject object1 , MesherObject object2)
Geometric object being object1 minus object2.

char()
Output a (unique) string representation of the MesherObject.
This can be used to perform comparisons between two
different MesherObject objects.
This function is to be completed.

display()
displays a short summary for a MesherObject object.
