//
//  Declaration of class PHRawOManager
//
//  Purpose: Write a node-tree into a PRDF file
//
//  Description:
//     - The default constructor sets all pointers to NULL. SetFile() would
//       have to be called in addition.
//     - The second constructor calls the setFile method to which it passes
//       on its arguments. In order of appearance:
//        1. The filename, type std::string, no default
//        2. The runnumber, int, defaults to 0
//        3. The buffersize, int, defaults to 100000
//        4. The eventlength, int, defaults to -1, in which case a quarter
//           of the selected buffersize will be chosen.
//        5. The compression-level. Values can range between 1 and 9, as in
//           gzip, the underlying compression program. Zero means no
//           compression at all, default is 3.
