Overhaul UI distribution selection
In this MR a new widget to select a distribution has been implemented to replace the generic mechanism of the property editor:
- new widgets
DistributionSelector
andDistributionSelectorDecorated
have a first implementation - a new version of the
DistributionDialog
namely the dialogEditDistributionDialog
has been made which includes some tweaks and a different interface
So far only for GISAS instruments the new distribution selector was used as an input widgets. Some more things have to been done to fully replace all occurrences of the property editor:
- for beams the UI is slightly different for the input of smaller numbers
- on some occasions only symmetric distributions must be used
- tool tips should be provided
