isValidElement not defined

In this file:

https://github.com/souporserious/react-motion-ui-pack/blob/master/src/is-element.js

Occurs when passing an element to component:

 <Transition component={<div />}} />

Fixed here a656c8d

To use a custom component you would need to pass something like this:

class CustomComponent extends Component {
  render() {
    return <div>{this.props.children}</div>
  }
}

OR

const CustomComponent = ({ children }) => (
  <div children={children}/>
)

<Transition component={CustomComponent}} />

Thanks for filing an issue! Sorry about that.
