+Description:
+
+This is a date formatting utility. The named template "format-date" takes 2 parameters:
+
+1. date - [required] takes an ISO date (2005-12-01)
+2. format - [optional] takes a format string.
+
+Format options:
+
+Y - year in 4 digits e.g. 1981, 1992, 2008
+y - year in 2 digits e.g. 81, 92, 08
+M - month as a full word e.g. January, March, September
+m - month in 3 letters e.g. Jan, Mar, Sep
+N - month in digits without leading zero
+n - month in digits with leading zero
+D - day with suffix and no leading zero e.g. 1st, 23rd
+d - day in digits with leading zero e.g. 01, 09, 12, 25
+x - day in digits with no leading zero e.g. 1, 9, 12, 25
+T - time in 24-hours e.g. 18:30
+t - time in 12-hours e.g. 6:30pm
+W - weekday as a full word e.g. Monday, Tuesday
+w - weekday in 3 letters e.g. Mon, Tue, Wed
+
+Examples:
+
+M       => January
+d M     => 21 September
+m D, y  => Sep 21st, 81
+n-d-y   => 09-21-81
+d/n/y   => 21/09/81
+d/n/y t => 21/09/81 6:30pm
