Date, Time, and Timespan Parsing Utilities

This module contains parsing support to create "human friendly"
``datetime`` object parsing.  The explicit goal of these routines is
to provide a multi-format date/time support not unlike that found in
Microsoft Excel.  In most approaches, the input is very "strict" to
prevent errors -- however, this approach is much more liberal since we
are assuming the user-interface is parroting back the normalized value
and thus the user has immediate feedback if the data is not typed in
correctly.

  ``parse_date`` and ``normalize_date``

     These functions take a value like '9 jan 2007' and returns either an
     ``date`` object, or an ISO 8601 formatted date value such
     as '2007-01-09'.  There is an option to provide an Oracle database
     style output as well, ``09 JAN 2007``, but this is not the default.

     This module always treats '/' delimiters as using US date order
     (since the author's clients are US based), hence '1/9/2007' is
     January 9th.  Since this module treats the '-' as following
     European order this supports both modes of data-entry; together
     with immediate parroting back the result to the screen, the author
     has found this approach to work well in pratice.

  ``parse_time`` and ``normalize_time``

     These functions take a value like '1 pm' and returns either an
     ``time`` object, or an ISO 8601 formatted 24h clock time
     such as '13:00'.  There is an option to provide for US style time
     values, '1:00 PM', however this is not the default.

  ``parse_datetime`` and ``normalize_datetime``

     These functions take a value like '9 jan 2007 at 1 pm' and returns
     either an ``datetime`` object, or an ISO 8601 formatted
     return (without the T) such as '2007-01-09 13:00'. There is an
     option to provide for Oracle / US style, '09 JAN 2007 @ 1:00 PM',
     however this is not the default.

  ``parse_delta`` and ``normalize_delta``

     These functions take a value like '1h 15m' and returns either an
     ``timedelta`` object, or an 2-decimal fixed-point
     numerical value in hours, such as '1.25'.  The rationale is to
     support meeting or time-billing lengths, not to be an accurate
     representation in mili-seconds.  As such not all valid
     ``timedelta`` values will have a normalized representation.

    This module returns a normalized time span value consisting of the
    number of hours in fractional form. For example '1h 15min' is
