# This module creates a formalized way to facilitate collection lookups.
# The default convention is that every workflow model has an associated
# collection with it:
#   WorkflowInstance::Scenario1::Collection
#   WorkflowInstance::Scenario2::Collection
#   OwnerInitialization::Scenario1::Collection
#   etc...
# But since we should be ready for unforseen circumstances a lookup method
# should be used in stead of a hard namespace lookup.
