    Mesh() -- Create an empty mesh object.

    This class allows one to manipulate the mesh object by adding new facets, deleting facets, importing from an STL file,
    transforming the mesh and much more.
    For a complete overview of what can be done see also the documentation of mesh.
    A mesh object cannot be added to an existing document directly. Therefore the document must create an object
    with a property class that supports meshes.
    Example:
    m = Mesh.Mesh()
    ... # Manipulate the mesh
    d = FreeCAD.activeDocument() # Get a reference to the actie document
    f = d.addObject("Mesh::Feature", "Mesh") # Create a mesh feature
    f.Mesh = m # Assign the mesh object to the internal property
    d.recompute()
