//
// This is an easy implementation of the Merging process (as root Macro)
//
// at the moment it reads a binary file ("rawtest.raw") which was written
// in the DAQ raw format.
//
// The data are stored in root container objects (classes derived from
// TObject like MRawRunHeader)
//
// This containers are written to a root file ("rawtest.root")
//
// It also demonstrates how you can loop over files in a single or more
// than one directory and process them. For details see MRunIter.
//

    // in the case you don't need parameter containers, all of them can

    // REMARK: Don't change the order of the two instantiations.
    //         I don't have an idea why, but here it crashes the
