Docs: $mdToast.simple() methods incomplete

[michaelbromley]

In the docs for the $mdToast service, the API reference for the $mdToast.simple() method lists a bunch of chainable methods exposed by the return object:

• content()
• action()
• highlightAction()
• capsule()
• theme()

However, the example source shows use of additional undocumented methods:

$mdToast.simple()
        .content('Simple Toast!')
        .position($scope.getToastPosition())
        .hideDelay(3000)

In addition there are also the event-handling methods onHide(), onRemove() & onShow() available to chain.
