logical operations on them. This commit provides the equivalent of NAND, NOT,
AND and OR.

Implement basic logical operations on predicates.
Implement limited function composure.

The function commited here is no where near as genral-purpose monadic--or
approximate--approach can provide. That's okay, for now.

Introduce triq quickcheck library.

This commit enables quick-check testing. Not all functions have been tested and

be. Progress for the future!

Remove travis-ci compilation on R15 and below.

We've found that rebar as bundled does not work on R14 and that dialyzer can
also fail on some R14 installations. Support for R14 is removed pending further
interest.
