+# Helpers to sort tables using clickable column headers.
+#
+# Author:  Stuart Rackham <srackham@methods.co.nz>, March 2005.
+# License: This source code is released under the MIT license.
+#
+# - Consecutive clicks toggle the column's sort order.
+# - Sort state is maintained by a session hash entry.
+# - Icon image identifies sort column and state.
+# - Typically used in conjunction with the Pagination module.
+#
+# Example code snippets:
+#
+# Controller:
+#
+#   helper :sort
+#   include SortHelper
+# 
+#   def list
+#     sort_init 'last_name'
+#     sort_update
+#     @items = Contact.find_all nil, sort_clause
+#   end
+# 
+# Controller (using Pagination module):
+#
+#   helper :sort
+#   include SortHelper
+# 
+#   def list
+#     sort_init 'last_name'
+#     sort_update
+#     @contact_pages, @items = paginate :contacts,
+#       :order_by => sort_clause,
+#       :per_page => 10
+#   end
+# 
+# View (table header in list.rhtml):
+# 
+#   <thead>
+#     <tr>

+#       <%= sort_header_tag('address', :width => 200) %>
+#     </tr>
+#   </thead>
+#
+# - The ascending and descending sort icon images are sort_asc.png and
+#   sort_desc.png and reside in the application's images directory.
+# - Introduces instance variables: @sort_name, @sort_default.
+# - Introduces params :sort_key and :sort_order.
