Merge pull request #8 from hackreactor/rearrange2

trying to make specs a little more clear
Merge branch 'rearrange' of https://github.com/hackreactor/recursion into rearrange
tweaks
wording
Replaced cdn libs
Updated getElementsByClassNameSpec; uses jQuery & converts nodelist to array
specs now search for correct class
Made some progress on stringify. Need to redo to figure out quotation marks
Need to fix use of .pop() for arrays, among other things...
Still hung up on the method for identifying what to recursively apply stringify to
Rewrote and significantly simplified. Now only test failing is object with "functions" and "undefined" keys.
stringify passes all tests! And I modified the weirdObjects test to see how undefineds were handled in arrays.
getElementsByClassName passes all tests!
Add a readme (automated commit)
