Detailed Description

A hit identifier with additional truth information.

In an addition to a unique identifier, an list of additional indices is stored. These can refer e.g. to particle indices or truth hit indices. Using indices instead of pointers allows more flexibility, i.e. we are not fixed to a specific object type when using e.g. pointers, and is more robust since no requirements on stable memory locations of the pointed-to objects are necessary (as would be the case for pointers).
