Set landmarks
=============

Landmarks can be set manually or using the landmark setter.

LandmarkSetter can be used to set landmarks interactively on a mesh.

Using LandmarkSetter with a list of shapes will set landmarks in correspondence.
One the landmarks are selected on the first shape of the list (the reference shape),
the user can select the same landmarks on the other shapes.
