readme / documentation should say what the default prop values are

[max-carroll]

I had to open up the source code to see what the default proptypes were,

static defaultProps = {
onChange: () => {},
onAuthenticate: () => {},
onAuthFailed: () => {},
scope:['https://www.googleapis.com/auth/drive.readonly'],
viewId: 'DOCS',
authImmediate: false,
multiselect: false,
navHidden: false,
disabled: false
};

We need to have a table which says what props there are and what the type is and what the default is
