closed as off-topic by Bill the Lizard♦ Oct 11 '13 at 18:30 This question appears to be off-topic. The users who voted to close gave this specific reason: "Questions asking us to recommend or find a tool, library or favorite off-site resource are off-topic for Stack Overflow as they tend to attract opinionated answers and spam.
