core design and user interface

i think we have enough data to create our first module. it will be a simple one that manages the content of the nominal records table. however, remember that it links to 2 other tables via the hierarchy so we now have to allow for them.

More importantly, though, we need to design the css and html that will be used throughout all future modules. Also included in that is the AJAX library and supporting php server files that interact with it.

The difference between calling a function in php and calling it in AJAX is that php can preload the files and then later call the function/class, whereas AJAX calls the function/class by requesting the url. so AJAX requires 2 files where php only requires 1 but this prevents duplication of any code.
