var level: Int

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.
