  # Public: Parse a MT940 string

  # data - The String containing the MT940
  # options - Hash with encoding options. Accepts the same parameters as String#encode!

  #
  # Examples
  #
  # Cmxl.parse(File.read('mt940.txt'), encoding: 'ISO-8859-1')
  # Cmxl.parse(mt940_string)
  #
  # Returns an array of Statement objects
