Short human readable instrument snapshot. #391
Description
@giulioungaretti
If we use instrument.snapshot() we get an overview of all parameters of an instrument, this is very useful for data storage. However, there is too much information to quickly scan over it.
Below I give an example, desired output first, current output after. I think the snippet below should (with some enhancements) be part of the base instrument class. Callable in the form of instrument.snapshot(concise=True).
Please let me know what you think.
Output of
