Detailed Description

Create a 1D Histogram (TH1F) and fill it for each event.

The histogram is stored in the current directory. You can set the current file and directory in any of the parents of this Processor or the top-level 'Cafe' controller via the .Output: or .Directory: parameters.

Configuration options:

• .Title: title [default: name]
• .Bins: NumberOfBins MinBin MaxBin [ default: 100 0.0 100.0 ]
• .Draw: DrawExpression [default:""]
• .Select: SelectExpression [ default: "1" ]
• .Weight: WeightName [ default: "" (which means we use 1.0 as weight) ]
