Base class for all the fit data types: Stores the coordinates and the DataOptions.

class holding the fit data points. It is template on the type of point, which can be for example a binned or unbinned point. It is basically a wrapper on an std::vector

private

This vector stores the vectorizable data: The inner vectors contain the coordinates data fCoords[0] is the vector for the x-coords fCoords[1] is the vector for the y-coords etc.

The vector of pointers stores the pointers to the first elements of the corresponding elements
