Summary:
Adding a model for malloc: we add an attribute "Allocated". This can be used for implementing memory leaks: whenever the variables get out of scope, we can check that if the variable has an attribute Allocated, it also has an attribute Invalid CFree.
Possibly we will need more details in the Allocated attribute, to know if it's malloc, or other allocation function, but we can add that later when we know how it should look like.
