Moving meshes

Sometimes, it is necessary to calculate equation in moving domains. In OOCSMP we can apply several operations (rotation, displacements and scale) to the meshes in the simulation loop. It is also possible to concatenate or detach several meshes.
Next there are two examples of moving meshes. In the first, two pieces approach until they collide and then move away until a certain distance, then the proccess is repeated. In the second the rotation operation is applied to a grid.
