properties in measurements should possible be called settings

[Pepe-Marquez]

Some of the Measurement entries have a sub-section called properties. This could be a confusing term, where scientists would expect physical properties derived from the measurements. A more intuitive term would be settings, to log the parameters set for the measurement.

Have to check if label works for subsection, if we need to migrate the schema this is a bit of work
I still feel like property is a generic term for settings, results and all sorts of qualities but if it is confusing we should change it

[RoteKekse]

properties = SubSection(
        section_def=PLPropertiesLibrary, label="Settings")

works and since "an attribute, quality, or characteristic of something." is a definiton of property i think it is ok to just relabel it and not do a schema migration
