0.7.0

Fixed

• St. Sebastian was missing in the French version of General Roman Calendar
• St. of Pietrelcina had incorrect rank in the Czech calendar
• Sanctorale#add: invalid attempt (i.e. an attempt raising an exception)
  to add a second (or n-th) celebration for a given date was causing
  inconsistency in the instance's internal state
• CLI: calendariumrom query wasn't printing celebrations of the highest
  ranks (spotted and fixed by Mike Kasberg @mkasberg)
• CLI: got rid of a deprecation warning of the i18n gem
  concerning I18n.enforce_available_locales (by Mike Kasberg @mkasberg)

Added

• data: General Roman Calendar in Spanish + Spanish locale (by Alejandro Ulate @CodingAleCR)
• data: optional memorials of St. Paul VI, Our Lady of Loreto, St. Faustina Kowalska
• data: diocese of Prague: optional memorial of Bl. Friedrich Bachstein and companions
• Day#weekday_name (by Ronald Walker @RonWalker22)
• Day#to_s, Celebration#to_s (by PJ Pollina @pjpollina)
• all sanctorale data files are provided with celebration symbols (available as
  Celebration#symbol when loaded)
• SanctoraleLoader loads the YAML front matter (if provided),
  to Sanctorale#metadata (new property added for this purpose)
• SanctoraleFactory methods merge not only sanctorale contents,
  but also metadata
• SanctoraleFactory.load_with_parents, Data#load_with_parents
  to conveniently load sanctorale file hierarchies based on their
  metadata (using key "extends")
• calendarium-romanum/cr defining ::CR shortcut constant
• huge improvement of the API documentation

Changed

• data files format: celebration symbols never more start with a colon
• Sanctorale#add throws ArgumentError on attempt to add a Celebration
  with #symbol which is already present in the given sanctorale
• all #each and #each_* methods defined in the gem return Enumerator
  if called without a block
