CGI (and other structural issues)

[meredithdutton]

Maintaining a web app as CGI with no templating is going to be unsustainable. Problems include:

• Changing style or JS library versions requires going through every one of the HTML files
• Lots of sys.path('..') calls make the code highly dependent on the current working directory; arranging the code into a Python package (in this sense would make this easier, particularly if ever we need to refactor.
• It's all very procedural. Using classes, modules and packages would help to modularise the code, encouraging re-use and extensibility.
