Changed Bayesian Networks to hold 5 states for each node

Discussed this a little with Afton, and since his code has 5 states for every node, we let it be so for now. Later on we might change this if computations become to slow.
Because most buildings do not need 5 states.
Changed names of bayesian networks
Added the old binary networks back, just as a backup
Merge branch 'import_dlib' into develop
