Script Summary: Places links to players' FanGraphs pages into Yahoo Fantasy Baseball leagues
Pretty self-explanatory. This will place an icon beside player names that links to their profile page on FanGraphs. It does this on Team pages, the Transactions/Recent Transactions lists, Players lists, etc.
It does this by adding a link that issues a search on FanGraphs; if the player name is unique, you're taken directly to their page. If the name is not unique, you will be presented with a clarification page. An obvious improvement would be to automatically select the active player (usually the first player in the list).
