Chained navigation request

[vkatz]

Be able to call to set specific path from navController including sub-navControllers

EG: navController.setPath(Root).then(Tabs).then(HomeTab,ProductTab).then(ProductDetails) --> 1st nc opens Root screen Root's screen inner NC(navController) opens Tabs Tabs's NC put HomeTab in backstack and opens ProductTab ProductTab opens ProductDetails

Pros:

• easy to use with complex navigation

Cons:

• will need to make dsl to generate tree
• can not controll subtrees? (eg: what if i want to put smth inside HomeTab's NC)
