Disharmony codecity example: The properties return Nil

Hi,

I am executing disharmony codecity example with the properties #isGodClass, #isBrainClass and #isDataClass. However, the properties return Nil and in the documentation we have: return nil if the property does not exist. I have some questions:

1- Where these properties are calculated? I have not found!
2- Where can I find the list badsmells implemented in codecity?
3- I would like implement new properties for disharmony codecity, Where to start?

My test code is this:

|  namespaces classes god  |
namespaces := (MooseModel root first allNamespaces).

classes := namespaces flatCollect: #classes.
"Testing isGodClass"
god := classes first isGodClass .

classes select: [:each | 
	each isGodClass
		ifTrue: [ Transcript 
			show: 'isGodClass: '; 
			show: each; 
			cr ]
		ifFalse: [ 
			each isBrainClass
				ifTrue: [ Transcript 
					show: 'isBrainClass: '; 
					show: each; 
					cr ]
				ifFalse: [ 
					each isDataClass
						ifTrue: [ Transcript 
							show: 'isDataClass: ';
							show: each; 
							cr ]
						ifFalse: [ Transcript 
							show: 'isNormalClass: '; 
							show: each; 
							cr ] ] ] ].

Thanks!
