new feature: create components as functions:

[sc0ttj]

• doing Foo = new Component(someState) now returns a function, not an object
• the function returned calls setState in its constructor
  • this means you can now set state using a new syntax - via the constructor: Foo({ count: 1 })
  • this in turns allows for nicer nested stateful components:
  • nested stateful components can now use the same syntax as stateless (plain function) components
• update in tweenState: allow shouldSetState to be boolean (not only func that returns boolean)
• updated examples, README, package.json, dist/, etc
