Module Deallocation

Provides an abstract class for modeling functions and expressions that deallocate memory, such as the standard free function. To use this QL library, create one or more QL classes extending a class here with a characteristic predicate that selects the functions or expressions you are trying to model. Within that class, override the predicates provided by the abstract class to match the specifics of those functions or expressions. Finally, add a private import statement to Models.qll.
