In order to make sure that we delete the isl context after all isl objects are delete, we introduce shared_ptrs to manage the life time of the context. We are going to distribute the shared_ptr to Dependences/IslNode which also create isl objects form the context. By doing this, we make sure the context is delete when we delete the last objects that create isl object from the context.
