Fixed #32 : concept groups are not correctly updated

Fixed #35 : Refactor test helper class (CNC, CC, CIO)
Fixed #36 : Concept values are not used when declared with variable expression
Fixed #37 : Objects in memory lose their values are restart
Fixed #38 : func(a=b, c) (which is not allowed) raise an exception
