Special object to approxiamte ridges on multi-dimensional histograms.
Ridge means that some coordinate in multidimensional histograms can be represented as function of another coordinate(s) like y = f(x). If one has histogram, build in (x,y) space, one can try to approximate function f by several way.
First simplest way, which works for two-dimensional way is to build TProfile from TH2 object, averaging data along y axis. Then TGo4FitDataProfile can be used to approximate TProfile by any kind of functional dependency.
Another way is usage of TGo4FitDataRidge object. It selects one of histogram coordinate and use histogram as a set of measured points y(x) with different statistical weights, reverse proportinal to bin content of histogram at (x,y). Then this set of points can be again approximate of any kind of functional dependency from one coordinate. This simplest case can be extend to N-dimensions. In this case one of coordinate is a functions of the rest. This means, that this corrdinate can be approximate by function with N-1 coordinates.
To obtain data, TGo4FitDataRidge object internally uses another TGo4FitData, which should provide histogram. Currently only TGo4FitDataHistogram object can be used for this purposes.

Creates TGo4FitDataRidge object with given name. Pointer on TGo4FitData object, which should provide histogramic data, can be specified. Also axis number, which uses as ridge coordinate, can be specified. By default y-axis is used as ridge.
