Initialise: The atoms in indices must be in the same order as in the RigidModel

this -- type(RigidBody), intent(inout)

at -- type(Atoms), intent(inout)

The atoms object to which the indices refer

indices -- integer, intent(in), dimension(:)

The indices of the atoms which make up the rigid body

RigidModel -- type(RigidBodyModel), target, intent(in)
