def _parse_field_list(fieldnames, include_parents=False):

Parse a list of field names, possibly including dot-separated subform
fields, into an internal ParsedFieldList object representing the base
fields and subform listed.

:param fieldnames: a list of field names as strings. dot-separated names
    are interpreted as subform fields.
:param include_parents: optional boolean, defaults to False. if True,
    subform fields implicitly include their parent fields in the parsed
    list.
