1417522 - ScreenGraph: allow multiple edges between the same pair of nodes, but with different predicates.

Status: NEW

(Firefox for iOS :: Build & Test, enhancement, P4)

Description

[James Hugman [:jhugman] [@jhugman]]

We should be able to support to direct routes between the a pair of nodes, with different gestures and different predicates. 

e.g. 

screenState.tap(app.button("URLBar.tabTrayButton", to: TabTray, if: "isTablet == true")
screenState.tap(app.button("TabToolBar.tabTrayButton", to: TabTray, if: "isTablet == false")

This is a placeholder to gather other examples before we should undertake this bug.

Currently not working on this. If anyone needs it, this is a reasonably large refactor, as edges are store in Map<String, GraphNode>().

For predicates to be involved, essentially, we need to change this to a Map<String, [GraphNode]>, which needs some careful, non mechanical refactoring.
