""" Remove duplicated faces.
Duplicated faces are defined as faces consist of the same set of vertices.
Depending on the face orientation. A special case of duplicated faces is
a fin. A fin is defined as two duplicated faces with opposite orientaiton.
If fins_only is set to True, all fins in the mesh are removed. The output
mesh could still contain duplicated faces but no fins.
If fins_only is not True, all duplicated faces will be removed. There could
be two caes:
If there is a dominant orientation, that is more than half of the faces are
consistently orientated, and fins_only is False, one face with the dominant
orientation will be kept while all other faces are removed.
If there is no dominant orientation, i.e. half of the face are positively
orientated and the other half is negatively orientated, all faces are
discarded.
Args:
vertices (``numpy.ndarray``): Vertex array with one vertex per row.
faces (``numpy.ndarray``): Face array with one face per row.
fins_only (``bool``): If set, only remove fins.
Returns:
3 values are returned.
* ``output_vertices``: Output vertex array, one vertex per row.
* ``output_faces``: Output face array, one face per row.
* ``information``: A ``dict`` of additional informations.
The following fields are defined in ``information``:
* ``ori_face_index``: An array of original face indices. I.e. face
``i`` of the ``output_faces`` has index ``ori_face_index[i]`` in
the input vertices.
