Create classrooms for multigrade classes

[Liviu Lalescu]

Sorry, ngo, but you have a very difficult/tiring style of asking/explaining the problem, and you always ask more and more...

You can add preferred room constraints or home rooms constraints. Preferred rooms override home rooms. A home room is respected if there is no preferred room for that activity and if the students set is a single one in that activity and it is exactly the same as in the home room constraint.
