add extended background estimation to the ihope pipeline
make lalapps_cbc_plotrates importable
add new files and utilities to pylal for extended background estimation
add plots for extended background estimation to ihope results page
Adds lalapps_cbc_plotrates to pylal/setup.py
In lal vars like lal.LAL_REARTH_SI had been renamed lal.REARTH_SI
so changed extended_background_utils.py to the new convention.
a bug on f21v3 and f21v3S fixed during SEOBNRv2 review
a bug on PeakDeltaTv2 fixed during SEOBNRv2 review
Merge branch 'master' of ligo-vcs.phys.uwm.edu:/usr/local/git/lalsuite
remove blip in EOBNRv2 frequency, due to RD matching point not on sampling points
Implement I0(snr^2 |autocorrelation|) likelihood
Use Gauss-Legendre quadrature over cos(i) and distance

Also add unit tests.
Tune thinning and number of samples per bin
Add option to postprocess MCMC samples with KDE
Match polarization sign in signal_amplitude_model & realize_coincs

I have checked that this is the sign convention that is used by
gstlal_inspiral.

This patch also adds a unit test for signal_amplitude_model.
Factor out awkward type punning
Conjugate nominal SNR to match convention in paper

Likelihood should depend on zhat * conj(z)
Adapt to renamed SWIG bindings
Use crude adaptive mesh refinement in place of TOA-only localization
Disable GSL 1.15-only code if GSL is too old
