Add README file
Update README so that Regard-Settings links to an example file
Initial work on storing events on the device before they are sent to
the main Regard service.
Saving to disk every 100ms instead of every 10ms will probably work better,
I think.
Log data to a file instead of sending it directly to the server
Start work on the cache flusher: iterate through the generated files
Actually read the events from the cache files
Actually send the event batches when flushing the files
Reduce the batch size to be kinder to 3G connections.
Ensure that cache files don't contain more than the number of events
specified by the batch size.
