Introduced new analysis class for MRO characterization.
Introduced new analysis class for MRO characterization.

Now:
Multiplexed_Readout_Analysis
    Analysis results of an experiment meant for characterization of multiplexed readout.
MultiQubit_SingleShot_Analysis
    Extracts table of counts from multiplexed single shot readout experiment.
    Intended to be the bases class for more complex multi qubit experiment analysis.
