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)

Basic idea is to create rout and allow to control flow of NavControllers

Pros: pretty simple syntax
Cons:

• you need to know whole ierarchy of your nc-s (do not have solution it so need to agree with this limitation)
• some one may try to do wired things rather then just navigation, option here is to make strict buider yet it going to be overcomplex
• a bit complex structure of follow flow loging inside nested NavController as next one may not be event created when current receive route signal, need to make smth like pendingflow logic
