06-jul-2004 NvE AliCalorimeter hit I/O only via the linear array to decrease filesize on disk
                and improve I/O speed.
                Internal temp. arrays used for hit sorting in AliDevice and AliEvent and array
                pointers returned instead of the arrays themselves. This will provide more
                flexibility in usage.
                Sorting and clustering procedures in AliCalorimeter modified to use TObjArray pointers
                to enable direct use of the AliDevice linear sorting facility.
                Default for AliDevice changed such that now all registered hits are by default owned
                by the AliDevice object.
