+Introducing Riostream.h

+Revision 1.20 2002/10/14 14:57:32 hristov
+Merging the VirtualMC branch to the main development branch (HEAD)
+
+Revision 1.13.6.2 2002/07/24 10:08:13 alibrary
+Updating VirtualMC
+
+Revision 1.19 2002/07/19 12:46:05 hristov
+Write file instead of closing it
+
+Revision 1.18 2002/07/17 08:59:39 jchudoba
+Do not delete subtasks when AliRunDigitizer is deleted. Owner should delete them itself.
+
+Revision 1.17 2002/07/16 13:47:53 jchudoba
+Add methods to get access to names of files used in merging.
+
+Revision 1.16 2002/06/07 09:18:47 jchudoba
+Changes to enable merging of ITS fast rec points. Although this class should be responsible for a creation of digits only, other solutions would be more complicated.
+
+Revision 1.15 2002/04/09 13:38:47 jchudoba
+Add const to the filename argument
+
+Revision 1.14 2002/04/04 09:28:04 jchudoba
+Change default names of TPC trees. Use update instead of recreate for the output file. Overwrite the AliRunDigitizer object in the output if it exists.
+
+Revision 1.13 2002/02/13 09:03:32 jchudoba
+Pass option to subtasks. Delete input TTrees. Use gAlice from memory if it is present (user must delete the default one created by aliroot if he/she wants to use gAlice from the input file!). Add new data member to store name of the special TPC TTrees.
+
+Revision 1.12 2001/12/10 16:40:52 jchudoba
+Import gAlice from the signal file before InitGlobal() to allow detectors to use it during initialization
+
+Revision 1.11 2001/12/03 07:10:13 jchudoba
+Default ctor cannot create new objects, create dummy default ctor which leaves object in not well defined state - to be used only by root for I/O
+
+Revision 1.10 2001/11/15 11:07:25 jchudoba
+Set to zero new pointers to TPC and TRD special trees in the default ctor. Add const to all Get functions. Remove unused constant, rename constant according coding rules.
+
+Revision 1.9 2001/11/15 09:00:11 jchudoba
+Add special treatment for TPC and TRD, they use different trees than other detectors
+
+Revision 1.8 2001/10/21 18:38:43 hristov
+Several pointers were set to zero in the default constructors to avoid memory management problems
+
+Revision 1.7 2001/10/04 15:56:07 jchudoba
+TTask inheritance
+
+Revision 1.4 2001/09/19 06:23:50 jchudoba
+Move some tasks to AliStream and AliMergeCombi classes
