[Rivet] missingEt variable in WFinder constructor

[Inês Ochoa]

Hi Frank,

The WFinder is defined as:

WFinder wfinder(-6.0, 6.0, 20.0*GeV, PID::MUON, 0.0*GeV, 1000.0*GeV, 
20.0*GeV, 0.1);

I can see that the documentation on WFinder now has some modifications 
on the list of arguments, but this is consistent with previous 
versions... I've also checked that the constituentLeptons()[0] pT does 
have a cut at 20 GeV.

Cheers,
Inês
