The structure for a jet made of pieces.
This stores the vector of the pieces that make the jet and provide the methods to access them

return the constituents (i.e.
the union of the constituents of each piece)
If any of the pieces has no constituent, the piece itself is considered as a constituent Note that as a consequence, a composite jet with no pieces will have an empty vector as constituents

return the error (uncertainty) associated with the determination of the area of this jet.
Be conservative: return the sum of the errors

true if this jet is made exclusively of ghosts.
In this case, it will be true if all pieces are pure ghost

disable the area of the composite jet
this can be used e.g. to discard the area of a composite jet made of pieces with non-explicit-ghost area since the area may by erroneous in that case
