+    The date template represents an interface shell for a date class
+    that is based on a year-month-day system such as the gregorian
+    or iso systems.  It provides basic operations to enable calculation
+    and comparisons.
+
+    <b>Theory</b>
+
+    This date representation fundamentally departs from the C tm struct
+    approach.  The goal for this type is to provide efficient date
+    operations (add, subtract) and storage (minimize space to represent)
+    in a concrete class.  Thus, the date uses a count internally to
+    represent a particular date.  The calendar parameter defines
+    the policies for converting the the year-month-day and internal
+    counted form here.  Applications that need to perform heavy
+    formatting of the same date repeatedly will perform better
+    by using the year-month-day representation.
+
+    Internally the date uses a day number to represent the date.
+    This is a monotonic time representation. This representation
+    allows for fast comparison as well as simplifying
+    the creation of writing numeric operations.  Essentially, the
+    internal day number is like adjusted julian day.  The adjustment
+    is determined by the Epoch date which is represented as day 1 of
+    the calendar.  Day 0 is reserved for negative infinity so that
+    any actual date is automatically greater than negative infinity.
+    When a date is constructed from a date or formatted for output,
+    the appropriate conversions are applied to create the year, month,
+    day representations.

+ -  %b - Abbreviated month name
+ -  %B - Full month name
+ -  %d - Day of the month as decimal 01 to 31
+ -  %j - Day of year as decimal from 001 to 366
+ -  %m - Month name as a decimal 01 to 12
+ -  %U - Week number 00 to 53 with first Sunday as the first day of week 1?
+ -  %w - Weekday as decimal number 0 to 6 where Sunday == 0
+ -  %W - Week number 00 to 53 where Monday is first day of week 1
+ -  %x - facet default date representation
+ -  %y - Year without the century - eg: 04 for 2004
+ -  %Y - Year with century
+
+ The weekday specifiers (%a and %A) do not add to the date construction,
+ but they provide a way to skip over the weekday names for formats that
+ provide them.
+
+ todo -- Another interesting feature that this approach could provide is
+         an option to fill in any missing fields with the current values
+         from the clock.  So if you have %m-%d the parser would detect
+         the missing year value and fill it in using the clock.
+
+ todo -- What to do with the %x.  %x in the classic facet is just bad...

+    and another class to represent a duration.  As a result, this class is
+    not appropriate for use when the number and duration representation 
+    are the same (eg: in the regular number domain).
+    
+    A period can be specified by providing either the begining point and 
+    a duration or the begining point and the end point( end is NOT part 
+    of the period but 1 unit past it. A period will be "invalid" if either
+    end_point <= begin_point or the given duration is <= 0. Any valid period 
+    will return false for is_null().
+    
+    Zero length periods are also considered invalid. Zero length periods are
+    periods where the begining and end points are the same, or, the given 
+    duration is zero. For a zero length period, the last point will be one 
+    unit less than the begining point.
+
+    In the case that the begin and last are the same, the period has a 
+    length of one unit.
+    
+    The best way to handle periods is usually to provide a begining point and
+    a duration.  So, day1 + 7 days is a week period which includes all of the
+    first day and 6 more days (eg: Sun to Sat).
