Pymodaq

The new main version highlights developpment of the Dashboard as the main starting point if pymodaq. It gives the opportunity to load preset_mode: configurations of a set of actuators and detectors. Then one can use extensions to do things with the detectors and actuators, that is:

* DAQ_Scan : for automated and synchronize scans
* DAQ_Logger: for data logging all all selected detectors into a single hdf5 file that could be local or on a distant server (to be done)

Many small bugs cleared after intense testing with people from the 3 days training course last 21/22/23 October 2019
