Get the histogram that may be stored in some object.

        This histogram is used to project from.

        Note:
            The output object could just be the raw ROOT histogram.

        Note:
            This function is just a basic placeholder and likely should be overridden.

        Args:
            observable (object): The input object. It could be a histogram or something more complex
            kwargs: Additional arguments passed to the projection function
        Return:
            ROOT.TH1 or ROOT.THnBase histogram which should be projected. By default, it returns the
                observable (input object).
