        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

                3 = parsed as a C{datetime}

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

f�t|	�S)'a�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  inputString: string
        @param inputString: natural language text to evaluate
        @type  sourceTime:  struct_time
        @param sourceTime:  C{struct_time} value to use as the base
        @type  version:     integer
        @param version:     style version, default will use L{Calendar}
                            parameter version value

        @rtype:  tuple or None
        @return: tuple of tuples in the format (parsed_datetime as
                 datetime.datetime, flags as int, start_pos as int,
                 end_pos as int, matched_text as string) or None if there
                 were no matches

    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.
