changed specs to compare iteration rather than toArray()

this seems like more of a fair comparison
pulled array counting out of lazy proper...

...and made it a monkeypatch in the specs
major refactoring into component files

also, now lazy is beating lodash on even small arrays in Chrome!
improved filter performance
wee little optimization for ArrayWrapper.toArray
refactored remaining sequence types using prototype pattern
teensy weensy change to UniqueSequence
cache Math.floor and Math.random for tiny perf win
renamed boot.js to init.js
add commas to benchmarks table (looks nice)
increased benchmark maxTime back up to 1s
updated README
