Moved the Code specification part (i.e., ECore classes FunctionalSpecification, FunctionalComponent and RelatedTo) to the Functional package of the mira model. Also cleaned the code for the functional specification editor and now no more RelatedTo Section as per Vincent's feedback (i.e., it feels awkward to see relations with the non-functional aspects in the functional aspect). Also made changes in the code where required for the code specification editor.
