Class describing the un-binned data sets (just x coordinates values) of any dimensions.

There is the option to construct UnBindata copying the data inside (in the base FitData class) or using a pointer to external data, depending on which constructor of the UnBinData class is used. It is recommended to copy the input data inside, since this will be more efficient and less error prone, since the input provided data will have to be kept alive for all the time the Fit classes will be used. In case of really large data sets for limiting memory consumption then the other option can be used with special care. Specialized constructor exists for using external data up to 3 dimensions.

When the data are copying in the number of points can be set later (or re-set) using Initialize and the data are inserted one by one using the Add method. It is mandatory to set the size before using the Add method.
