Get the revision of the actual fitter implementation.
This is needed for revision logging. Implementation should look like:
return std::string( "$Rev$" );
In case you don't reimplement the calculateResidulas methods you should also state the revision of this base class:
return std::string( "$Rev$ ; TrackFitterBase ") + TrackFitterBase::getRevision();
Don't forget to switch on the 'svn Rev' property for this file:
svn propset svn:keywords Rev TrackFitterImpl.cc
Reimplemented from marlintpc::TrackFitterBase.
