class AliHEPDataParser: public TObject

           Implementation of Class AliHEPDataParser

  This class is used to save the content of hisograms/graphs in the
  HEP data format and viceversa. The HEP data format is not strictly
  defined and there are many variants, the class only support a few
  of them. More will be added as needed.  The input can be a set of
  2 TH1, TGraphAsymmErrors or TGraphErrors (one for the stat and one
  for the syst error). If the second one is a null pointer, only the
  stat error is printed. The class can also import hepdata ascii
  file (very preliminary)

Double_t RoundToSignificantFigures(double num, int n)
 Rounds num to n significant digits.
 Recipe from :http://stackoverflow.com/questions/202302/rounding-to-an-arbitrary-number-of-significant-digits
 Basically the log is used to determine the number of leading 0s, than convert to an integer by multipliing by the expo,
 round the integer and shift back.
