As we get ready to make a real release of the new code... here is a list of quantities that will be expected as
output within a Root ntuple.
Below are tables containing the expected ntuple items, divided by subsystem....
Each table contains a "DONE" column to denote that we are now writing
this quantity out to a Root ntuple.
Also, note, that we may desire to rename some of these items...for instance CsI
=> Cal and Veto => ACD
