of Error and BC Branches
Error
Branch (SttE) -- All error and status related values. To store as
much information as possible some individual leaves contain multiple
pieces of information packed into them.
Leaves:
One entry per crate in run per event. Numbers in brackets
correspond to bit-ranges for leaves with packed values.
