Here's a fix for the fact that compose was composing functions in the wrong order, and modified test cases to test for it.
Previously
__::compose($f, $g)would return a function$hsuch that$h($x) = $g($f($x).Instead
__::compose($f, $g)should return a function$hsuch that$h($x) = $f($g($x).This is more consistent with the behavior of Underscore.js and is also closer to mathematical conventions.
