 Encapsulate Gero's routines for counting D*                          
   (prior part of GFHistManip)                                        
                                                                      

 N(D*) from scaling up wc due to factor between startBack and endBack
 and subtracting background in region dmLow to dmHigh
 0: N(D*), 1: sigma(N), 2: signal to background ratio 3: scale for wcHist

 N(D*) from scaling up wc due to factor between startBack and endBack
 and subtracting background in region dmLow to dmHigh (but result from fit!)
 0: N(D*), 1: sigma(N), 2: signal to background ratio 3: scale for wcHist

 N(D*) from N(D*) in between dmLow and dmHigh
 and subtracting background fit in region dmLow to dmHigh (adjusted to next bin border)
 0: N(D*), 1: sigma(N), 2: just == 1.
 sigma is not correct,at least not if wcHist as been scaled before!

 returns factor that has to be applied to wcHist to get same number of entries
 as dstarHist from startback to endBack
 assuming same binning of both hists!!!!!
 0. if wcHist is empty in that range
