bb250e7205 Much better strategy for calling native Array methods. 
Compare an object's function with === to the native
version before calling it.  That is, don't just assume that
because an object has a 'filter' property thats a function,
that we should call that in _.filter().

Expose the native methods found as _.native

On the way towards being able to turn off native implementations,
though there are tradeoffs...

76bbfddd95 our #reduceRight delegates to #reduce after reversing. 
no need to reimplement it.

also, reduceRight is worthless :)

c43de549ba Create #alias method, callable on any object, _ by default. 
While I'm not a fan of making abstractions where a simpe solution
exists, I think this is good as it makes a public API for extending
underscore, therefore making it "ok" to make your own alias names.

Also give us some future proofing in case we ever add in hooks on
method definition. For example, right now if you add a method
or make an alias in user code, it isn't added to the wrapper prototype.

Added tests and inline docs, no external docs

7ec8d12d6c rename underscore methods after the native [] method names, aliases for ruby versions 
Even though the native methods have worse names (forEach, every, some),
since this library is trying to smooth over the native language it makes
more sense to use the native names, and provide aliases for more sensible
names from other languages, not the other way around.

Note this doesn't change any external usage, it just makes more sense.

This should also be useful for abstraction purposes for building underscore
functions, something like:

  addFn('some', {has_native: true, our_version: function () {...}})

this way we could feature detect on load for native versions and build a
function, and also have the option to turn off native versions for testing
our implementation.

I Also standardized the comments to look like:
  Delegates to JavaScript 1.x's native y if available.

59a4f49bfa Make internal var each = _.each 
We use it everwhere, so this should be a slight speedup
but make code more readable
