#include <BaseIndexedConstituentUserInfo.h>
BaseIndexedConstituentUserInfo is an base implementation of IConstituentUserInfo. It provides means to attach an label and vertex to a fastjet pseudojet. Subclasses add the pointer to an IParticle or other object.
The label is held by index (along with a pointer to the label index to decode it). The vertex is missing. The index 0 corresponds to no label and negative values indicate the constituent is a ghost, i.e. has very low energy and so has little effect on the jet four vector.
