   1.3.5 - Allow lower-case 'wait for', 'value' columns.
   1.3.4 - Allow 'loop' for parallel columns.
   1.3.3 - Allow space after 'loop' or 'range'.

   1.3.1 - Table scan 'time' as alternative for 'seconds'.
   1.3.0 - Table scan 'loop' support.
   1.2.1 - Table scan '+p' update.
           Used to accumulate _all_ the parallel commands
           on a line. Now only combines adjacent +p columns.
   1.1.1 - Allow site-specific ScanSettings to override
           getDefaultSettings() such that is replaces
           the PV name, preserving that name.
   1.1.0 - Table scan adds "# Line .." and "# End" comments,
           and also uses the original line number
           in error messages, even for expanded rows.
   1.0.9 - Scan settings match the complete name,
           i.e. the pattern is anchored, as if
           there was an implied "^...$" around the pattern.
           Before, it was an implied "^.." only.
   1.0.8 - Workaround for 'event executor terminated'
   1.0.7 - Support ScanClient.submit(.., queue=False)
   1.0.6 - Fix ranges like 'range(1,2,1)' which failed because expansion contains only one item

   1.0.3 - Add getDevice() to Loop, Set, Wait commands
   1.0.2 - Fix: Default tolerance of Loop, Set, Wait commands
   1.0.1 - Fix: Set & Loop command set <wait>false</wait> when no readback desired
   1.0.0 - Initial Release
