getOutput is called to determine the value for the named output at the current state of the system. The proper way to do this is to not use the inputValues. Instead useinputChanged to supply a black box with its inputs.
This is a list of BigInt values that are in the same order as the outputDependencies lists them
The concrete type of this output

There is one bit of hand-waving magic to make black boxes work when they have internal state. In order to satisfy the single pass assignment to every wire, black boxes with state must specify that their inputs depend on their outputs, in order to get the correct topological sort. See the AsyncResetBlackBox test to see an example of how this was done.
This method will be called for each input symbol of the black box.

This is the template for writing Scala functions that implement the behaviour of a black box. Implementing classes should add internal variables to hold any state information.
