Let's do this.

Note that setting MECAB_MARGINAL_PROB for the request type will only affect output when node parsing.

Also note that parsing speed will suffer a 3-5 times decrease than the default mode.

--marginal works in concert with --theta, but apparently does not have any affect when using --partial or boundary constraint parsing.

Unit test added. Done and ready for 1.0.0 release.
