 * $Log: StppLMVVertexFinder.h,v $
 * Revision 1.14  2017/02/14 22:00:41  smirnovd
 * Squashed commit of the following clean-up changes:
 *
 * See master branch for details.
 *
 * - Remove commented code for debugging
 * - Removed extra validation; it is done at construction
 * - No need to include header for apple OS
 * - Removed pointless assert
 * - Use standard portable type name
 * - Remove unused header math_constants.h
 * - StMinuitVertexFinder: Remove abandoned member function
 *
 * Revision 1.13  2016/08/18 17:46:14  smirnovd
 * Squashed commit of the following refactoring changes:
 *
 * Date:   Wed Jul 27 18:31:18 2016 -0400
 *
 *     Removed unused arguments in UseVertexConstraint()
 *
 *     In StiPPVertexFinder and StvPPVertexFinder this method does nothing
 *
 * Date:   Wed Jul 27 16:47:58 2016 -0400
 *
 *     Make old UseVertexConstraint private virtual and call it from its public replacement in the base class
 *
 *     also mark methods as private explicitly
 *
 * Date:   Wed Jul 27 16:52:02 2016 -0400
 *
 *     Removed unused private data member mWeight
 *
 * Date:   Wed Jul 27 16:50:42 2016 -0400
 *
 *     Prefer base class static beamline parameters rather than this class private members
 *
 * Date:   Wed Jul 27 16:21:49 2016 -0400
 *
 *     StPPVertexFinder: Got rid of unused private beamline parameters
 *
 *     The equivalent measurements are available from the base class
 *     StGenericVertexFinder
 *
 * Date:   Wed Jul 27 16:19:19 2016 -0400
 *
 *     StPPVertexFinder: For beamline position use equivalent static methods from parent class
 *
 * Date:   Wed Jul 27 16:05:50 2016 -0400
 *
 *     StGenericVertexMaker: Assigning once is enough
 *
 * Date:   Mon Aug 15 10:43:49 2016 -0400
 *
 *     StGenericVertexFinder: Print out beamline parameters
 *
 *     Print beamline values as extracted from the database before any modification.
 *
 * Date:   Wed Jul 6 15:33:02 2016 -0400
 *
 *     Stylistic changes and minor refactoring
 *
 *     Whitespace and comments for improved readability
 *     s/track/stiKalmanTrack/
 *
 * Date:   Wed Jul 6 15:28:16 2016 -0400
 *
 *     StPPVertexFinder: Switched to cleaner c++11 range loop syntax
 *
 * Date:   Wed Jul 6 15:22:14 2016 -0400
 *
 *     StPPVertexFinder: Minor c++ refactoring
 *
 *     - Removed unused counter
 *     - c-style array to std::array
 *
 * Date:   Wed Jul 6 15:20:11 2016 -0400
 *
 *     Deleted commented out code
 *
 *     Removed unused #include's StMinuitVertexFinder
 *
 * Revision 1.12  2012/12/12 22:09:58  fisyak
 * add sys/types.h include for APPLE
 *
 * Revision 1.11  2010/01/26 21:01:49  fisyak
 * Clean up, switch from bit mask to attributes
 *
 * Revision 1.10  2005/07/19 21:57:40  perev
 * MultiVertex
 *
 * Revision 1.9  2005/06/21 02:16:36  balewski
 * multiple prim vertices are stored in StEvent
 *
 * Revision 1.8  2004/09/03 00:09:08  jeromel
 * Modified code to Implement Init() and SetMode() and allow passing a switch
 * to chose the vertex finder from within the same code implementation. Was
 * needed for ppLMV (one implementation, two algorithm)
 *
 * Revision 1.7  2004/09/01 18:45:01  balewski
 * ppLMV5/4 switch added
 *
 * Revision 1.6  2004/08/05 22:08:04  balewski
 * toward working point
 *
 * Revision 1.5  2004/08/04 21:57:56  balewski
 * toward smarter ppLMV5
 *
 * Revision 1.4  2004/07/24 02:57:40  balewski
 * clean up of ppLMV, CTB-util separated
 *
 * Revision 1.3  2004/07/23 02:24:39  jeromel
 * Oops ... Worng swithc (had twice Minuit). Now corrected.
 *
 * Revision 1.2  2004/07/23 01:00:52  jeromel
 * Removed methods/data members (moved in base class) + doxygenized
 *
 * Revision 1.1  2004/07/21 01:53:18  balewski
 * first

 *
 * ppLMV use new set of params
 *  INT:  CtbThres/ch=2   MinTrkPonits=10   i2=0   i3=0   i4=0   i5=0   i6=0   i7=0   i8=0   i9=9999
