different normalization in different bands
test script for make_model
make flux/unc arrays float64 to avoid problems on Yeti
add wavelength regions for different normalization parameters
Merge branch 'med_res' into band_norm

change normalization at ends of spectrum

rather than set normalization to 1 at the ends, just extend the
wavelength bins so the first and last bins cover the low and high
ends of the wavelength range
check path, to see which computer I'm on
minor adjustments to properly use the wavelength-dependent normalization all the way through
more test files
don't need band-by-band normalization when I'm just fitting one band
100 random samples instead of 200
actually getting a full batch running with the various normalization parameters
Merge branch 'band_norm' into med_res
pickle Marley models without any conversion (do that later)
