Hey Zorandir, thank you a lot for your contribution!

I looked quickly at the the code, and found a couple of issues.

First, the "usage" docsStrings of the new functions are full of StyleBoxes.
I can't read them in my Mathematica installation. =/
Could you remove all formatting from the docStrings, please?

Also, as a general best practice, long expressions such as:

Apply[Or,#&/@Map[Part[#,1]==1-(Part[#,2])&,Select[MapThread[If[#1===#2,"X",#1==#2]&,{BaseTemplate[2,r],t}],Not[#==="X"]&]]]

...should be divided into private functions, or variables using Module.

I'm gonna try out ExceptionTemplate and ComplementTemplate and let you know if I find any issue.

Zorandir, I made a few changes to the code, and merged it with this technique.

I thought this pull request would be closed as merged, but I guess I was wrong.

I'm gonna close this one, but all your commits are in the project's history squashed into c438cf1.

Thanks for the contribution! =]
