add jquery, parse library. Created like-button-javascript outline. Initialized viewer-id
changes for fetching likes from server
changes for counting likes per post, and whether viewer has voted on the post
actually drew the like buttons and wrote code to save the like to parse
hooked up saving likeAction and displaying the number-of-likes
added some fixes for like button; also my editor cleared extraneous whitespace
fixes to improve styling, layout and mobile handling of the like button
namespaced LikeActions in parse by domain. Need to revisit to ensure logic works when loaded within iframes
