-- compressOrbits gets all the current Tag-0 start information from
-- the NFA states; then it loops through all the Orbit tags with
-- compressOrbit.
--
-- compressOrbit on such a Tag loops through all the NFS states'
-- m_orbit record, discarding ones that are Nothing and discarding
-- ones that are too new to care about (after the cutoff value).
--
-- compressOrbit then groups the Orbits records by the Tag-0 start
-- position and the basePos position.  Entries in different groups
-- will never be comparable in the future so they can be processed
-- separately.  Groups could probably be even more finely
-- distinguished, as a further optimization, but the justification will
-- be tricky.
--
-- Current Tag-0 values are at most offset and all newly spawned
-- groups will have Tag-0 of at least (succ offset) so the current
-- groups are closed to those spawned in the future.  The basePos may
-- be as large as offset and may be overwritten later with values of
-- offset or larger (and this will also involve deleting the Orbits
-- record).  Thus there could be a future collision between a current
-- group with basePos==offset and an updated record that acquires
-- basePos==offset.  By excluding groups with basePos before the
-- current offset the collision between existing and future records
-- is avoided.
--
-- An entry in a group can only collide with that group's
-- descendants. compressOrbit sends each group to the compressGroup
-- command.
--
-- compressGroup on a single record checks whether it's Seq can be
-- cleared and if so it will clear it (and set ordinal to Nothing but
-- this this not particularly important).
--
-- compressGroup on many records sorts and groups the members and zips
-- the groups with their new ordinal value.  The comparison is based
-- on the old ordinal value, then the inOrbit value, and then the (Seq
-- Position) data.
--
-- The old ordinals of the group will all be Nothing or all be Just,
-- but this condition is neither checked nor violations detected.
-- This comparison is justified because once records get different
-- ordinals assigned they will never change places.
--
-- The inOrbit Bool is only different if one of them has set the stop
-- position to at most (succ offset).  They will only be compared if
-- the other one leaves, an its stop position will be at least offset.
-- The previous sentence is justified by inspection of the "assemble"
-- function in the TDFA module: there is no (PostUpdate
-- LeaveOrbitTask) so the largest possible value for the stop Tag is
-- (pred offset). Thus the record with inOrbit==False would beat (be
-- GT than) the record with inOrbit==True.
--
-- The Seq comparison is safe because the largest existing Position
-- value is (pred offset) and the smallest future Position value is
-- offset.  The previous sentence is justified by inspection of the
-- "assemble" function in the TDFA module: there is no (PostUpdate
-- EnterOrbitTags) so the largest possible value in the Seq is (pred
-- offset).
--
-- The updated Orbits get the new ordinal value and an empty (Seq
-- Position).

-- the starting index while doing so, and compares the earliest start
-- with the stored winners.  (part 3) If some winners are ready to be
-- released then the future continuation of the search is placed in

-- The "newWinnerThenProceed" can find both a new non-empty winner and
-- a new empty winner.  A new non-empty winner can cause some of the
-- NFA states that comprise the DFA state to be eliminated, and if the
-- startState is eliminated then it must then be respawned.  And
-- imperative flag setting and resetting style is used.
--
-- A non-empty winner from the startState might obscure a potential
-- empty winner (form the startState at the current offset).  This
-- winEmpty possibility is also checked for. (unit test pattern ".*")
