a bit of a mess right now; commencing project take-a-step-back...
wrote up the basic gist of my idea in the README
changed input.input to input.values (less confusing, maybe?)
now the README is sort of implemented!
styled demo page a bit
added Marathon object
fixed sumRecursive example
updated browser example to work w/ new Marathon object
added very silly Race.addCommas method

This is of course a prime candidate to be replaced once I go and build

added marathonComplete callback to Marathon object
updated page w/ a little description + GitHub ribbon
