/**
 * The type system in powercycle is a 4-level ladder:
 *
 * - Component :: SourcesObject -> SinksObject
 *   Any function
 * - InlineComponent :: SourcesObject -> SinksObject
 *   Any function
 * - StateMapper :: State -> State
 *   Produced mainly with the $map function - function with a symbol flag
 * - StateReference :: Proxy sugar which resolves to a StateMapper in
 *   powercycle::traverseAction
 * - StreamReference :: Proxy sugar which resolves to a Stream in
 *   powercycle::traverseAction
