[Magritte] Description properties

Hi, adding properties to descriptions is a simple but long work. You need to: - add a boolean description (class side) - add a default method (class side) - write accessors (instance side) - write action methods starting like 'beSorted' (instance side) - write testing methods (instance side) When looking at accessors: MAToManyDescription>>ordered ^ self propertyAt: #ordered ifAbsent: [ self class defaultOrdered ] it seems to me it was just a DictionaryAccessor after all. So I tried to use this. - I implemented #at: and #at:put: in MAObject (that were just calling #propertyAt: and #propertyAt:put). - I wrote a new constructor in MADescription: #dictionaryKey:label:default:priority:) - I replaced some properties descriptions by a call to the new constructor. All the tests still worked (not sure any line of what I changed were called during the tests). But then, I didn't know how to replace all the methods that need to be written. Do you have any idea? -- Damien Cassou
