def read_header_list(self):
return self._FITS.read_header(self._ext+<NUM_LIT:1>)<EOL>
Read the header as a list of dictionaries.

You will usually use read_header instead, which just sends the output
of this functioin to the constructor of a FITSHDR, which allows access
to the values and comments by name and number.

Each dictionary is
    'name': the keyword name
    'value': the value field as a string
    'comment': the comment field as a string.
