Input and Output of Reshaping

[rosoba]

Chaining of Reshaping steps into Design Pipeline is based on the
state transitions from
x_0 ... initial positions
u_0 ... trial displacement for the simulation
x_00 = x_0 + u_0 ... initial positions for the simulations
u_1 ... final displacement state after simulation
x_1 = x_0 + u_1 ... final
x_t[] = array of positional vectors for all increments within the Reshaping

Check this and write a test for this.
