Hi Metal team,
I'm having trouble determining how to pass an onClick event to each tab.

Looking through both the demo, and the source, I don't see how I can pass an OnClick event to any of the tabs. Either in the tabs object array, or when declaring the component.

I've added the tabs as an array of objects
[{label: 'test', onClick: this.handleOnClick}]
^ This doesn't work.

<Tabs tabs={tabs} onClick={this.handleOnChange} />
^This doesn't work

We should follow the standard for tab panel accessibility.

We currently just follow the usual tab order, but that's not how tabs are expected to work, and can be really annoying for a page that has many tabs, specially when the user doesn't really want to change the tab, just access something in the active tab's content.

The standard is to only allow regular tabs to access the active tab. To switch between tabs the arrow keys should be used instead.
