Merge branch 'release/v0.0.1' into develop
Fix bug introduced by deleting galileo.py
Fix some docopt usage patterns
gls and bls both work with bis

There is a new option for per to calculate the periodogram of the
CCF Bisector Inverse Slope. But with the bls this is still not
working correclty because of the frequency sampling calculation.
Keep extras full set; but this needs work
restrict now changes extras arrays, but needs testing, is it efficient\?
improve SNR calculation in bls when considering bis
minor changes in dawson fabrycky routine
implements fwhm periodograms
Merge branch 'feature/PerOtherQuantities' into develop
some verbose output in read
playing with gen alg; more read output
nicer plot after fit
--force option in per to recalculate the periodogram
limit newton iterations to e<0.8; I think it went nuts sometimes
some tests for get_rvn
gen working for one, two (and more?) planets.

fixed a lot of things in the genetic algorithm; generalized it to
more than one planet; fixed output.
Needs work both on prior ranges and in the way to include more than
one observatory (with vsys for each one).
save fit info after gen; new plot of the fitted curve; minor changes in gen core
playing with parameter priors in gen
trying to do phased curves, nothing yet
