Detailed Description

Weighted Bin for any histograms.

Unlike the standard weighted bin, the values are stored in float variables to reduce memory usage on large histograms.

The value of this bin is: value = SUM[ weight ] The error of this bin is: error = sqrt( SUM[ weight*weight ] )

By default the gravity center of all the data points in this bin is the middle of the bin.
