v0.2.0

Changes

• Added semver as blip.version
• Added an .each method to loops to allow running a block of code on the first tick of each iteration of the loop.
• Allow setting of default rate and gain for clips using clip.rate() and clip.gain()
• Added a .tickInterval setter/getter to the loop interface, which allows the loop interval to be set in terms of a specific time interval rather than divisions of a minute.
