//      Documentation:
//              This class is responsible for checking the crossing of a surface
//              that could be the  external boundary of a volume  or the external
//              surface of a sphere.
//              It is used to check if an adjoint particle reaches the external
//              surface or reenter the sensitive region delimited by the adjoint
//              source.
