lalinference: have other likelihoods save SNRs to IFOdata struct
bayespputils: expect lower-case SNR names
ligolw_inspinjfind:  add content handler
binjfind:  aesthetics
glue.ligolw:  tiny performance improvement

- avoid some attribute look-ups when chaining through I/O wrappers
ligolw_inspinjfind:  update copyright notices
ligolw_inspinjfind:  tie internal bisection search to --time-window

The internal bisection search for events near an injection was fixed to +/- 1 s, but when the --time-window option was create its default value was set to 9s, so many injections people were expecting to be able to find were not being found.  This patch ties the bisection search to the command line option.
ligolw_inspinjfind:  edit --match-algorithm docs
ligolw_inspinjfind:  import tools --> as xlaltools
ligolw_inspinjfind:  add --revert feature
ligolw_inspinjfind:  move compare func wrappers to app

out of library code.
ligolw_inspinjfind:  port verbosity to ProgressBar
ligolw_inspinjfind:  perf. improvements

- use early bailouts in coinc match functions
- build sets directly in coinc match functions instead of building lists and converting to sets
ligolw_inspinjfind:  use bisection search to find matching coincs
ligolw_inspinjfind:  retrieve offset vectors

- not used for anything yet, but implies a bit of error checking to ensure
  the document's time_slide table isn't busted, and will be used in the
  future when injections are done into time-shifted data
