Initial automated reporting

[RobertPincus]

It would be neat to ensure that each YAML file phase file is sensible. That might mean

• segment times (other than ground) lie between take-off and landing times
• only one primary kind per segment(?
• ??

It would also be neat to make light-weight diagnostics at each push. One might be plan and/or side views of the segments for each flight, organized in some sensible way.

@RobertPincus can set this up to run for each commit once scripts are complete.

Another test: a time window can't belong to two segments of the same kind.

If we adopt the idea of subsets (profile ascending as always part of a profile) we need to check that the two tags are applied to the same segment, or that the subset is part of a longer segment described by the superset.
