withSetter("assign") ?

[Coffee2JS]

What's the difference between

prop<string>('').withSetter()

and

prop<string>('').withSetter('assign')

?

Current doc only talks about the first one, but the 'assign' variant is still in the api... I stumbled across it when upgrading to latest version & looking at changelog.

prop<string>('').withSetter() automatically creates a setter method for you, e.g. for a prop named x you can do model.setX(...) without defining setX yourself, whereas prop<string>('').withSetter('assign') lets you assign a new value, e.g. model.x = ....

Would the change in #269 make it clearer?
