docs: Called from the static initializer of a reloadabletype, allowing it to connect itself to the parent type, such
  that when reloading occurs we can mark all relevant types in the hierarchy as being impacted by the reload.
  
  @param child the ReloadableType actively being initialized
  @param parent the superclass of the reloadable type (may or may not be reloadable!)
