    # Add a method to the String class so we can easily format phone numbers.
    # This enables:
    #   "31612341234".phony_formatted # => '06 12341234'
    #   "31612341234".phony_formatted(:spaces => '-') # => '06-12341234'
    # To first normalize a String use:
    #   "010-12341234".phony_formatted(:normalize => :NL)
    # To return nil when a number is not correct (checked using Phony.plausible?) use
    #   "010-12341234".phony_formatted(strict: true)
    # When an error occurs during conversion it will return the original String.
    # To raise an error use:
    #   "somestring".phone_formatted(raise: true)
