It will produce a histogram with the distribution using the formula contributions.
For the moment this method will just fill one node (without fParameter). But if the component expression depends on the node parameter it might require further development.
TODO: The histogram is filled just by evaluating the formula, but it would be more realistic that we fill the histograms with a number N of entries that mimic a MC generation scheme similar to TRestComponentDataSet.
