Board component

[lastmjs]

We should consider encapsulating board init inside of a component. We can then deal with synchronization easily be waiting to init children until the board is ready.

• Initialize children when board is ready
  • Children should be passed the function they need to initialize their children, since these components will be user-created, and we do not want them to have to deal with importing and calling a function to initialize their own children
• Change the way default options are handled, they do not need to be specified by the component, the jfive constructor will handle them
• Handle IO plugins
• Handle all methods (should some be accessed through properties?)
• Automatic tests
  • Add tests for all methods and for repl getter
  • Figure out how to use spies/mocks effectively
  • Use mocks for the event handler tests and below
• Write documentation

Also, this should help modularized the io plugins
