Describes the flow of ObsUnits (sets and SBs). Basically this will define an ordered sequence of these, complete with conditions to determine flow ("if either SB1 or SB2 has completed..."), or time patterns that define the flow ("SB2 2 hours +/- 30min after SB1", or regular measurements over some period). The details of how these are expressed are TBD, so the controlScript attribute is a placeholder for the moment.
