Detailed Description

Write out a planar cluster collection into a root file to avoid immense long vectors, each cluster is one entry in the root file for optimised data writing speed The event number is part of the written data.

A common file can be provided for the writer to attach his TTree, this is done by setting the Config::rootFile pointer to an existing file

Safe to use from multiple writer threads - uses a std::mutex lock.
