        The DataSet class stores a set of data, usually in XY format, along with all the properties describing the data, such as input parameters to the simulation etc.

        Members are:
            * x, y - These contain the data and are expected to come as lists of Numpy arrays
          by many functions operating on DataSets. However, for user-supplied functions,
          other ways of representing data may be used.
            * props - This is a dictionary of properties describing the dataset.
