+/// Smart-WiFly-WebServer is the creation of a web server using a WiFly module.
+///
+/// This is a working version, but it is not using the standardized wifly
+/// library, which would not work for me... I had to make a number
+/// of changes to get it to work well. After trying to minmimize those
+/// changes, additional improvements became more and more clumsy, so
+/// I have now been working to refactor where it makes sense, even as
+/// it further deviates from the mbed-library version.
+///
+/// I created this because I couldn't find one that worked and wanted to
+/// learn the WiFly module. There are a lot of possible improvements:
+/// @li I think I'm not using the Socket interface as fully as I should.
+/// @li I would like it to be faster (the interface from mbed to wifly is
+///     limited to 230400 baud before it drops chars. HW handshake could
+///     improve this, but the HW handshake pins on the LPC1768 are not
+///     both brought out.
+/// @li I would like to integrate this with the rtos.
+/// @li If a page has multiple components (e.g. images), it appears
+///     unreliable. It doesn't see the request for the extra component.
+///     A poor workaround, for images, is to use a javascript to post-
+///     load them. This is fundamentally a constraint of the WiFly module.
+///
+/// history:
+/// @li 20130602 added .txt to the supported types (e.g. robots.txt), so
+///         revised the credentials to .crd, which is an unsupported type
+///         therefore won't be delivered to the user.
