Detailed Description
Simple -like fitter which sets all errors to 1.
The value of the sum of the squared residuals is not useful to estimate the errors, but the minimisation should work.
The CalculateResiduals() function from TrackFitterBase is used.

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.
The documentation for this class was generated from the following files:
- TrackFitterSimpleMinimizer.h
- TrackFitterSimpleMinimizer.cc
