Test program for the class TUnfoldBinning.

read a simple binning scheme and create/test bin maps

Binning scheme:
=================================
TUnfoldBinning "binning" has 20 bins [1,21] nTH1x=20
TUnfoldBinning "branch1" has 12 bins [1,13] nTH1x=12
distribution: 12 bins
"x" nbin=4
"y" nbin=3
TUnfoldBinning "branch2" has 6 bins [13,19] nTH1x=6
distribution: 6 bins
"x" nbin=3
"y" nbin=2
TUnfoldBinning "branch3" has 2 bins [19,21] nTH1x=2
distribution: 2 bins
"x" nbin=2
CreateEmptyBinMap
