About OB

[stéphane ducasse]

hi colin

I have the impression that I do not have the complete OB in 3.9.  
Normally I published the version you cleaned.
273.mcz

Could you check and let me know?
It seems that the following classes are missing:

   OBClassCategoryNode
   OBMetagraph
   OBClassNode
   OBMethodCategoryNode
   OBEnvironmentNode
   OBMethodDefinition
   OBClassActor
   OBMethodNode
   OBCategoryActor
   OBClassDefinition
   OBSystemBrowser
