# Functions defining the MenuSequence that will be placed into ChainSteps
# Generate a menu sequence given a set of jet sequences to schedule.
# The hypo may be set up as a preselection hypo, in which case it will
# record a single DecisionObject, instead of one per jet.
# A hypo may alternatively be configured to passThrough, such that
# the hypo will not retrieve any jets and simply pass.
#
# In these functions, we:
#   - First generate the data dependencies for the full jet reco sequence.
#     These come in the form of a dict of JetDefinitions, which are
#     used to define inter-step data dependencies (cluster collections etc).
#     The JetDef is accompanied by a final jet collection name, which is
#     filtered into a vew container to accelerate the hypo
#   - Then pass the JetDefinitions into the configurator functions,
#     which return ComponentAccumulator.
#   - When ChainSteps are created by JetChainConfiguration.getStep,
#     the MenuSequence generators will be wrapped in a deferred call
#     so that when constructing the full HLT menu, we don't regenerate
#     identical sequence configurations repeatedly.
