        @brief The IMdtSegmentFinder is an interface (pure virtual class) for accessing MDT segment finders.
        Each segment finder is an AlgTool that is called by MDT segment maker tools, receives hit and road
        information in station coordinates and returns segment candidates that the segment maker can fit
        the hits to, perform other post processing tasks, and return them upstream.
 
        The interface consists of a single function, findSegments -
 
        @code
        virtual SegCandVec* findSegments(DCVec &dcvec, CLVec &clvec, MdtMultiChamberGeometry &geometry, Road &road);
        @endcode
