        Splits the given C{datetimeString} into tokens, finds the regex
        patterns that match and then calculates a C{struct_time} value from
        the chunks.

        If C{sourceTime} is given then the C{struct_time} value will be
        calculated from that value, otherwise from the current date/time.

        If the C{datetimeString} is parsed and date/time value found, then::

            If C{version} equals to L{VERSION_FLAG_STYLE}, the second item of
            the returned tuple will be a flag to let you know what kind of
            C{struct_time} value is being returned::

                0 = not parsed at all

                2 = parsed as a C{time}
                3 = parsed as a C{datetime}

            If C{version} equals to L{VERSION_CONTEXT_STYLE}, the second value

        Takes the given C{source} date, or current date if none is
        passed, and increments it according to the values passed in
        by month and/or year.

        This routine is needed because Python's C{timedelta()} function
        does not allow for month or year increments.

f¡ t|	ƒS )(a³  Utilizes parse() after making judgements about what datetime
        information belongs together.

        It makes logical groupings based on proximity and returns a parsed
        datetime for each matched grouping of datetime text, along with
        location info within the given inputString.

        @type  version:     integer
        @param version:     style version, default will use L{Calendar}
                            parameter version value

                 datetime.datetime, flags as int, start_pos as int,

    Default set of constants for parsedatetime.

    If PyICU is present, then the class will first try to get PyICU
    to return a locale specified by C{localeID}.  If either C{localeID} is
    None or if the locale does not exist within PyICU, then each of the
    locales defined in C{fallbackLocales} is tried in order.

    If PyICU is not present or none of the specified locales can be used,
    then the class will initialize itself to the en_US locale.

    if PyICU is not present or not requested, only the locales defined by
    C{pdtLocales} will be searched.

        The current time is used as the default and any specified
        item found in self.re_sources is inserted into the value
        and the generated dictionary is returned.
