Removing old methods not needed after alias refactoring.
Merge pull request #3 from buzzdecafe/master

all & some.

Not quite sure of `all`.  Seems to me that `all([]) => true`
Adding booleans (still untested), reversing assert order to match Node.assert expectations, and fixing `all`.
Adding tests for boolean functions.
Fixing append and reverse, adding flip, still no tests for that (or for append), adding filter and its tests.
Added partials and `reject`
contains and uniq
