Detailed Description

The RemnantData class is not a normal ParticleData class.

It should never be handled directly by the interface but is automatically created and assigned to an object of the SoftRemnant sub-class of Particle. The SoftRemnant in turn is not a proper Particle, but rather a place holder for what is left of a colliding particle after one or several partons has been extracted. To be able to retrieve properties of the SoftRemnant through its ParticleData the RemnantData is used to dynamically keep track of this.

The RemnantData is initialized by the ParticleData corresponding to the colliding particle. For each particle which is extracted the charge charge is changed accordingly. Also the colour charge is changed, but only such that the coloured(), hasColour() and hasAntiColour() returns relevant information. The actual colour can only be singlet, (anti-)triplet or octet.

When created the RemnantData object must be given a RemnantDecayer object and a single DecayMode object will be created with this Decayer.
