Substance is a JavaScript library for web-based content editing. It provides building blocks for realizing custom text editors and web-based publishing systems.

  A FileProxy represents a proxy from a FileNode to the real resource.
  As real resources may need to be fetched, the FileProxy typically has
  multiple internal states.
