This is companion pull request to webwork2 PR #767. It addresses bugs that occur in multiAnswer and matrix answer evaluators. Many of the bugs arose because of the change to using the answer evaluator as the primary the primary object for a given answer —rather than the answer blank. (This helps regularize the increasing number of answer evaluators that use more than one answer blank — e.g. matrices and multiAnswer. At the moment I don’t know of any answer evaluators that share an answer blank — if that comes up there are mechanisms to deal with it on a case by case basis — but no organized protocol.)
