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.
Will this actually work? You do not import pyplot in here. Besides that, try to only keep your changes in the main to functionality that supports the dm integration. All the plotting, animating, etc in the main-loop I'm handling in a separate item.
