Spent most of the week trying to integrate Joel's event marker graphs with
the interactive AMP graphs that he also wrote. Took me a while to get my
head around the levels of indirection, but I've pretty much tracked down
the correct locations in the code to be able to update events on the fly
in the same way that the data is presented. Will be linking this in with
the output of various anomaly detection algorithms to better visualise the
quality of the detected events.

Also made the event detection on multiple AMP time series a bit more
robust after it failed to continue running over the weekend. If for some
reason erg is unreachable or the data returned doesn't make sense it
should be able to continue running. Looking forward to getting some useful
events and being able to quickly investigate the data behind them!
