//
// Fcl-based tool to return Index vectors indexed by an index, e.g.
// event lists indexed by run.
//
// Parameters:
//   LogLevel - Message logging level (0=none, 1=ctor, 2=each call, ...)
//   Entries - vectors of indices in format [RRR, EE1, EE2, ...]
//             RRR is the map index
//             [EE1, EE2, ...] is the mapped vector
//             If a map index appeared ealier, the new entries are appended.
