The method string used in rave::Factory has the following general structure:

{{{
finder-name:value-name:value-...
}}}

Sometimes nesting is required (e.g. to configure "sub-algorithms"):

{{{
finder-name:value-name:(value-name:value-name:value)....
}}}

As for the finders, the following algorithms are defined:

 * kalman
    KalmanVertexFitter This is the simple linear kalman filter that takes no extra parameters. 
 * avf
   AdaptiveVertexFitter The avf respects the following parameters:
   * sigmacut: The value for [ = sqrt (2) ] at which a track has track weight=0.5. 
   * Tini: Initial temperature in the annealing schedule. 
   * ratio: The ratio with which the temperature falls in each iteration step. 
   Default is: avf-Tini:256-ratio:0.25-sigmacut:3 
 * tkf
    TrimmedKalmanVertexFinder The tkf respects the following parameters:
   * ptcut: Cut in the tracks' pT, given in GeV/c. 
   * vtxcut: Bla FIXME 
   * trackcutpv: Bla FIXME 
   * trackcutsv: Bla FIXME 
   Default is: tkf-ptcut:0-trkcutpv:0.05-trkcutsv:0.01-vtxcut:0.01
