time to make each public

[buzzdecafe]

working with the DOM has convinced me of the need for an each method on ramda.
The DOM does not lend itself to immutability. Or referential transparency. Or elegance. so this is one vote for exposing a bit of impurity (gasp) in the lib for the sake of practicality.

Note that since we are not using native array methods (e.g. slice) internally, we can use ramda seamlessly with NodeLists et al.

Thoughts?

No major objection, although the public name should probably be forEach. Probably the internal name too. jQuery should not ever be responsible for how we choose to name things!

done, and .idx too.
