EMU: tpar files: scripts to restore files to known versions

[Tom-Willemsen]

On discussion with the EMU instrument scientists, we have agreed to store TPAR (temperature parameter) files in the configurations git repository.

As an instrument scientist, I would like instrument scripts to do the following:

• Mark a known set of the TPAR files as "good" (for example, using a git tag or branch?)
• Restore files to this known set (e.g. using git checkout from a known state, saved by the above command)

This is so that, if a user changes a TPAR file during an experiment, the scientists can change them back to a known state afterwards

Notes:

• This is not required by EMU for the upcoming cycle (this has been checked with the scientists). It is a "nice-to-have" addition that would make certain workflows easier.

This was mentioned to me today, under SECI each TPAR file was stored in a manager mode protected sub-configuration, so a fresh copy was always copied out when a configuration was changed. This was the "associated files" option in SECI.
