module Activity::Schema
# Helps organizing the structure of the circuit and allows to define steps that
# might be inserted in a completely different order, but it's experimental.
#
# Translates linear DSL calls that might refer to the same task several times into a linear "drawing instruction"
# that can be consumed by Schema.bla.
#
# This class is experimental.
