eqexam: A Matching-type Problem

With a little effort, a problem* environment can be exploited to create a matching-type problem. The eqe_matching.pdf is an exam created from the exam environment of the eqexam package; the exam has one matching-type question. A second demonstration file named eqe_matching-rt.pdf has the same question but the entries in the columns are randomized.  The markup of these files requires the eqexam package dated 2021/02/26 or later. The matching-type question is completely compatible with the eqexam system, such questions respond correctly to all of eqexam options.
