-- **`springTension`** _(Integer)_ - a number between `1` and `100`, controls the amount of tension on the spring that guides the scroll animation - see [example](http://facebook.github.io/rebound-js/examples/#graph-canvas).

 - **`children`** _(ReactComponents)_ - each top-level child component should have a `tabLabel` prop that can be used by the tab bar component to render out the labels. The default tab bar expects it to be a string, but you can use anything you want if you make a custom tab bar.
 - **`tabBarUnderlineColor`** _(String)_ - color of the default tab bar's underline, defaults to `navy`
