Beam energy is assumed to be 10.6 everywhere

Look it up via RCDB (or CCDB, if we decide to add the "corrected" beam energy there)

In the first instance you should probably just have a SetBeamEnergy function which propogates to the algorithms (probably in ChangeRun), with the users responsible for calling. Most/all analyses should have a method of getting the beam energy and it should not necessarily be iguana's job.

The tests will need to know the beam energy, however, or at least assume a default. Perhaps we can restrict Iguana's usage of CCDB and RCDB to the tests, but we may eventually have algorithms that are reliant on CCDB and RCDB.

Perhaps we should do the opposite then and consider if iguana can interface to the dbs as part of its scope. I would be quite happy removing it from clas12root ! And probably it will need database access.
