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.
In the paper "Performance of the Keck observatory adaptive-optics system" it is indeed multiplied by the constant. In the assignment document somehow it is missing.
