(** Methods for creating a procdesc from a method or function declaration
    and for resolving a method call and finding the right callee *)

(** When the methoc call is MCStatic, means that it is a class method.  When it is MCVirtual, it
    means that it is an instance method and that the method to be called will be determined at
    runtime. If it is MCNoVirtual it means that it is an instance method but that the method to be
    called will be determined at compile time *)
