/* Vertex Finder Tool.
 
    Abstract class which provides the possibility to implement more than one 
    vertex finder tool (every vertex finder tool inherits from 
    this class).
 
    Base class for secondary vertex finders inside jets (takes as input:
    1) primary vertex
    2) jet direction (jet momentum is provided)
    3) list of tracks
    and gives as output:
    --> VxSecVertexInfo class
