made some perf improvements for shuffle, uniq, and zip

also added more tests and updated SpecReporter w/ the ability
to display failure information
scrapping CompactIterator since it's redundant
fixed dumb mistake in DropIterator
nope... it was the "fix" that was dumb
added some tests + some style
added docs to index.html

seriously, that was way harder than it should've been
center them images
moved index.html to root folder
forget sorting the results
tiniest styling change ever
added lodash for comparison tests

phew, lodash is a lot faster than underscore!
baby steps
adding GitHub ribbon to master branch
