v0.2.0

Breaking Changes:

• clientId is now treated a string instead of an int. (It is still a number, but this is an implementation detail which should not be relied upon).
• connectionClose Server event has been dropped (listen to exposed socket instead)
• close event(s) are now closed to distinguish from the close event many core I/O elements use.

New:

• A custom transcoder can now be provided. This allows for specialized encoded/decoded of messages when
  JSON just won't do. (#1)
• Added Example for high-throughput/noisy client implementation.

Enhancements:

• Greatly expanded docs -- especially the API docs (always more work to do here!)
• More specific errors in some send failure cases
• Clarified event api
• Improved handling of abrupt disconnects. What can't be handled is now documented.
• Underlying net.Socket is now exposed to give applications direct access to socket events when
  they matter.
