V2.0

[dbonino]

• Refactoring of the Controllable tree to account suggestions / issues fixed by DogOnt forks, e.g., ThinkHome.
• Extension of environment modeling to account spaces different from Buildings.
• Extraction of systems (former house plants) from the Controllable tree, and definition of a new tree rooted at TechnicalSystem
• Definition of "belongsTo" relations and restrictions to mark which controllable may be belongTo or be part of a Technical System.

The latter change needs further refinement. In particular we are checking if the belongsTo objec property always expresses part-of relations. In such a case, re-factoring to partOf is foreseen
