Added M3 functions to Core.rsc for constructors

- Get all constructors from M3 model; constructors(M3)
- Get all constructors from class in M3 model; constructors(M3, loc)
- Is M3 entity X a constructor?; isConstructor(M3)
Added compilationUnits M3 function to Core.rsc
- Gets all compilationUnits of an M3 model; compilationUnits(M3)
