Add a python program to stack BOSS spectra and a program to plot the stack
save both unweighted and weighted stacks
save stacked data as hdf5 file
Add signal to noise stack, stack variance and normalization option
remove debug print
save pixel values for forest and non forest wavelengths at z 2.4
fix wavelength scaling
calculate pull mean and rms
calculate pull var instead of rms, debug sqrt warning
fix bug saving wrong data array as pull
clean up stack array names. add z range to hdf5 output datasets
fix summing of weighted squre flux
Extend spectrum normalization specification, organize hdf5 hists into group
Calculate weighted flux variance
fix wfluxvar typo
add program to bin 2d rest vs obs wave histograms
comment out rest statistics
add options to specify rest wavelength range
add options to control y binning in reststack, generalize output, update plotstack to parse generalized output
remove debug print statement
