--event-chisq to plot an snr and chisq on the snr chisq plots

- allow the threshold to be adjusted manually (default is the current
  behaviour, which is to set the threshold from the lower bound of the
  extinction model's domain of validity)

- weren't used for anything, adds baggage to the code.  in the future, it
  might be worth adding an option to select which offset vector to process,
  but none of what this patch removes would be used for that

- a bunch of code was added related to the alphabet soup approach, and then
  commented out.  this patch removes it.  it can be reverted later if
  somebody wants to resurrect it

- define a stand-alone method to implement the ranking statistic's
  fast-path cut, and use that method for both the cut itself *and* the
  coinc sieve passed to thinca to ensure the two are always identical.
- this is the first step in making this cut much *MUCH* more agressive.

- add option to cluster after coincidence. Note the biggest SNR and biggest LR (if available) trigger is kept
- fix bug in max over lr and snr
- optionally limit the far of single candidates by live time for online analysis
- make online 'clustering' before LR computation
- fix clustering
