 /**
  * An object used by instances of [ResolverVisitor] to resolve references within
  * the AST structure to the elements being referenced. The requirements for the
  * element resolver are:
  *
  * 1. Every [SimpleIdentifier] should be resolved to the element to which it
  *    refers. Specifically:
  *    * An identifier within the declaration of that name should resolve to the
  *      element being declared.
