Flask

I decided to use the Flask microframework for the web interface on the Linux embedded system project I am working on. The UI is very simple (it ran in a PIC microcontroller before) so Flask looks like the right choice for this project. There's no database required (not yet anyway...) but the web UI does access the digital I/O. There are no special timing requirements so the I/O can be done directly from the POST handler, unless something unforeseen comes up.
