Test's need to be cleaned up

Due to how Object.observe is implemented the current test suite fails on any browser that does not have a native implementation of Object.observe. All tests need to give Object.observe opportunity to see the changes come into effect.

Tests for Array, Object, and Observable are now in place. Tests are segmented on functionality (do Array's work, do Object's work, etc) and named as tests..js so they group well in file trees and listings.
