Detailed Description

TFile service.
The file attribute is a TFile that can be used in several analyzers.
The file is closed when the service stops.

Example configuration:

output_rootfile = cfg.Service(
  TFileService,
  'myhists',
  fname='histograms.root',
  option='recreate'
)

Constructor & Destructor Documentation

__init__()

def tfile.TFileService.__init__	(		self,
			cfg,
			comp,
			outdir
	)

cfg must contain:
- fname: file name 
- option: TFile options, e.g. recreate

outdir is the output directory for the TFile

comp is a dummy parameter here.  
It is needed because the looper creates services and analyzers 
in the same way, providing the configuration (cfg), 
the component currently processed (comp), 
and the output directory. 

Other implementations of the TFileService could 
make use of the component information, eg. the component name.
