Detailed Description

Class to store comments in BLOB without any data.

Author

Nils Gollub nils..nosp@m.goll.nosp@m.ub@ce.nosp@m.rn.c.nosp@m.h

This is a specialesed TileCalibDrawer class that holds only the comment fields but no calibration data. It should only be stored in the COOL comment channel (see TileCalibUtils class).
