-Note: Should be discarded in favour of the fastcgi approach
-
-SQLite approach to interfacing with web frontend:
-
-*Main program reads in sensor data and updates the sqlite database 
- with this new data
-*When sqlite.php is called, the database is queried, and the values returned
- to the caller (format can be anything you like)
-*You could have a main webpage, ie index.html
-*Whenever you need to update the page, you use jQuery (or other method)
- to call sqlite.php, which returns the data needed
-
-This works because SQLite allows concurrent access to the database
-(or it should).
