+  /*!
+    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.

+    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).

+    So, in fact multiple time types can be created for a time_system with
+    different construction policies, and all of them can perform basic
+    operations by only writing a copy constructor.  Finally, compiler 
+    errors are also shorter. 
+    
+    The real behavior of the time class is provided by the time_system
+    template parameter.  This class must provide all the logic
+    for addition, subtraction, as well as define all the interface
+    types.
