creating new branch for dm

The branch includes test file (test.py). It works fine if we use the test file (with given lenslet position). However, calling it from main.py still needs parameters from others. Furthermore, the dm function now requires additional parameter (paramsActuator) in order to work.
Even there I don't see a clear multiplication sign. It says sig1 = 0.54 subaperture, but does that mean 0.54 times the spacing between actuators?
And in equation 3 from that document there is a 470 micro meters at the end of the equation. Is that the multiplication you are doing?
I'm just trying to understand where the computations are coming from.
