//
//       ALFA_GloRec class implementation
//
//
//
//
//  PURPOSE:
//  - reconstruction of global tracks in ALFA
//
//
//  INPUT JOB OPTIONS:
//  - data type: DataType
//  - patterns of tracks through detectors: TrackPathPatterns
//  - analysis root file: AnalysisFile
//  - name of input collection: InputLocRecCollectionName
//  -   name of output collection: InputGloRecCollectionName
//  -   name of truth info collection: TruthEventCollectionName
//
//  OUTPUT:
//  - GloRecEvCollection of ALFA_GloRecEvent
//  - some analysis histograms
//
//  OTHER INFO: 
//  Uses aux. classes
//  1) AlfaLocalHit
//          - stores one local hit
//          x, y, z, pot name, pot number, pointer to ALFA_LocRecCorrEvent
//
//  2) AlfaLocalHits
//      - stores stl vector of AlfaLocalHit
//      - may contain stl vector of itself to define path of the track
//          ... the path is defined as pattern string
//          ... string = names of detectors separated by _ or X for any possibility
//          ... there's one pattern at a time for the object, it can be reset
//      - if the pattern is applied m_paths (of AlfaLocalHits) is filled
//          ... there may be more paths for one pattern
//              (if there were more local hit combinations)
//      - in job options the TrackPathPatterns may contain multiple patterns
//          separated by comas (without spaces), it is then looped over all 
//          patterns 
//      - detector names are ALFA standard names:
//          B7L1U A7L1U  B7L1L A7L1L B7R1U A7R1U B7R1L A7R1L
//
//  3) AlfaTrackCand
//      - is declared with ONE path from AlfaLocalHits object 
//      - contains x and y halfway between the pots and slope x' and y' of the gloabl track
//      - contains two pointers of ALFA_LocRecEvent the track is constructed from
//
//  There many methods of the above aux. classes not described at the moment.
//  Things are under development.
