Joshua Harlow 166bfff48c Add a directory/filesystem based persistence layer
Add a nice non-memory-based but also non-db based
persistence layer which is another good example of
how a persistence layer can be created (and used).

Example directory structure:

  /books
  /books/247c5311-d4ec-461b-9e76-51830d6a75b2
  /books/247c5311-d4ec-461b-9e76-51830d6a75b2/metadata
  /books/247c5311-d4ec-461b-9e76-51830d6a75b2/flows
  /books/247c5311-d4ec-461b-9e76-51830d6a75b2/flows/25f18828-a067-411e-9035-8217536f925d
  /flows
  /flows/25f18828-a067-411e-9035-8217536f925d
