class_docstr: Interface class for storage systems.
  
  A key -> multiple distinct values mapping.
  
  Keys and values are binary data.
docstr: Move value from key src to key dest. Equivalent to delete(src,
  value) followed by save(src, value) but may have a more efficient
  implementation.
  
  Note that value will be inserted at dest regardless of whether
  it is currently present at src.
