Idea for SN direction precision estimation

[ast0815]

We could probably extract an estimate for the statistical uncertainty of the direction on a supernova-by-supernova basis using the bootstrapping method: https://en.wikipedia.org/wiki/Bootstrapping_%28statistics%29

1. Trigger the SN
2. Reconstruct all events
3. Calculate SN direction
4. Create sample from SN events (with replacement) of same size (i.e. resample)
5. Calculate resampled SN direction
6. Repeat from 4 until sufficient resampled directions
7. Spread of resampled directions is measure for statistical uncertainty of main SN direction
