Hi,
Lots of users like the midas::odb interface for reading from the ODB in manalyzers. It currently doesn't 
work offline however without a few manual lines to tell midas::odb to read from the ODB copy in the run 
header. The code also gets a bit messy to work out the current filename and get midas::odb to reopen the 
file currently being processed. This would be much cleaner if manalyzer set this up automatically, and then 
user code could be written that is completely ignorant of whether it is running online or offline.

The change I suggest is in the `set_offline_odb` branch, commit 4ffbda6, which is simply:

                }


It happens at the point where the ODB record is already available and requires no effort from the user to 
be able to read the ODB offline.

Thanks,

Mark.
