class Hash
  # Cleans up the hash and returns the result. It performs the following
  # operations:
  #
  # * Values with keys ending in _at and _on are converted into Times and
  #   Dates, respectively
  # * All keys are converted to symbols
  # * Value strings 'true', 'false', and 'none' are converted into
  #   true, false, and nil, respectively
