Description

ModelChooser is introduced in 2.0 to match JoinTree in query with JoinTree in model.

Currently, we first use ModelChooser to decide the model, then choose cube from the selected model. The cubes in other models are never considered. Chances are there when selected model cannot provide capable cube while non-selected model can. So it's still necessary go through all models
