    New application framework

    Add initial scaffolding to support applications with non-hard-coded
    table names and registers.

    Includes:

    * 'wiring' configuration (vertices and edges)

    * Decorator for new applications, with States, Entrypoints, Exitpoints,
      and public and private variables.

    Includes code for reading and parsing this information, and connecting
    the 'external' tables, i.e. the exitpoints of one app to the entrypoint
    if the next app.
