docs - MyComponent() does not create component instance

[ghost23]

Hi,

in the docs here:

https://github.com/facebook/react/blob/master/docs/docs/ref-02-component-api.md#reactcomponent

it says, that:

"Component classes created by React.createClass() return instances of ReactComponent when called".

But it turns out, React.renderComponent(...) actually creates the component instance, at least the one you work with. I think, the docs should reflect that.

Good catch. We updated a lot of other places as we evolved the API but obviously missed at least one. Let us know if you see any more!
