restore_sample: How to modify existing sample?

[prjemian]

When the sample already exists, hkl.util.restore_sample() will raise ValueError. How to modify existing sample (if user option allows)?

Note the collections.namedtuple._replace() method.

[prjemian]

As the original comment suggests, replace the object may be the best method.

Need to look at the libhkl code for an interface to update, replace, or delete sample (configuration).

[prjemian]

Short answer: That feature is not in the Python interface nor is it in libhkl.

@mrakitin : Implementation of this capability (modify existing sample) requires some refactoring of how sample (and reflections) are handled by the Python code. Long term, this information. For example, see #143, which is in the v1.1 Milestone. I suggest moving this issue to the v1.1 milestone (marked for completion by 2021-12-01, tentatively).
