/** Aggregate cake with all inter-dependent modules assembled together.
  * Each instance of this class contains independent IR context, thus many
  * instances can be created simultaneously.
  * However, the inner types declared in the traits are path-dependant.
  * This in particular means that ctx1.Ref[_] and ctx2.Ref[_] are different types.
  * The typical usage is to create `val ctx = new Scalan` and then import inner
  * declarations using `import ctx._`.
  * This way the declaration will be directly available as if they were global
  * declarations.
  * At the same time cake design pattern allow to `override` many methods and values
  * in classed derived from `Scalan`, this is significant benefit over
  * *everything is global* design.
