/// FemRepresentation. The IndexedLocalCoordinate must be related to an FemElement (the index is an FemElement id and
/// the local coordinates are the barycentric coordinates of the nodes in this FemElement).
/// It is used, for example, as a helper class for filling out the MlcpPhysicsProblem in
/// Fem3DRepresentationContact::doBuild, which constrains the motion of Fem3DRepresentation at a frictionless contact.
