The contravariant subtyping rule for the PerformanceCritial annotation was meant to document the code but can be very too verbose on exisiting project. It is also not necessary as we can get this annotation from the supertypes. I am disabling it for now, but keep the code in case we want to revive it at some point in the future.

This allows to run the checker and get feedback about potential expensive call stacks without having to annotate first all the methods that are overriding PerofrmanceCritical-annotated methods

Summary: public
Use the analysis summary to store call stacks from PerformanceCritical-annotated methods to Expensive-annotated methods.
This use the on demand scheduling in order to make sure that the summary of the callee is always analyzed before the callers.

This adds the following subtyping rules:
- methods that are not annotated with Expensive cannot be overwritten by a method annotated with Expensive
- methods annotated with PerformanceCritical must be overwitten by method annotated with PerformanceCritical

Just works by running the analysis bottom-up and promoting any method as virtually annotated with `Expensive` whenever one of its callee is annotated with `Expensive`

Summary: public
This is an initial version of the Expensive checker which only report violations on direct calls. The main objective is to setup all the files for this new checker.
The next steps are:
1) run the checker in interprocedural mode
2) Save in the summary of a method foo() the annotation attribute Expensive if a direct callee of foo is annotated with Expensive
3) Check that Expensive is enforced by subtyping, i.e. check that non-expensive method cannot be overwritten by a method annotated with Expensive
