5. dev2rsp
Transforms (device points) to (reference or 3D points)
																rsp = dev2rsp(dev) 
																rsp = dev2rsp(dev,lambda) 
																rsp = dev2rsp(dev,lambda,idx)
															
Inputs / outputs
- dev = 2xN points of the device surface.
 - lambda = Scalar parametrizing the light rays at pixel dev.
 - lambda = []. The output rsp is a point on the reference plane.
 - lambda ~= []. The output rsp is a point of the 3D space.
 - idx = Indice of the employed pose.
 - rsp = 2xN or 3xN. Corresponding points on the ref plane or 3D space.
