Since we are relying on the out-degree of nodes (i.e. consumers.length), this method should only be called after the forward edges have been constructed.
Returns the absolute path to a component instance from toplevel.

A backend(Backend.
A backend(Backend.scala) might generate multiple module source code from one Module, based on the parameters to instanciate the component instance. Since we do not want to blindly generate one module per instance the backend will keep a cache of each module's implementation source code and discard textual duplicates. By walking the nodes from level zero (leafs) to level N (root), we are guarenteed to generate all Module/modules source text before their first instantiation.

Hardware module that is used to sequence n producers into 1 consumer. Priority is given to lower producer
Example usage: val arb = Module(new Arbiter(2, UInt())) arb.io.in(0) <> producer0.io.out arb.io.in(1) <> producer1.io.out consumer.io.in <> arb.io.out
