Branching Execution

[ImLucasBrown]

Is your feature request related to a problem? Please describe. Would be nice for a node to have multiple exec in/out connections.

Describe the solution you'd like A single node would be able to select which exec out path to follow during its compute. This would give us the ability to have n# of branching logic exec chains.

Additional context This may need some very carful thought as it may create a breaking change to the current graphs.
