Major procedures
Run all the time-series analysis routines for a BRUCE dataset.
Read in stellar spectra from FITS files
read in BRUCE model spectra from FITS files
extract a lightcurve lc(t) from the 2d spectrum f(w,t)
convert 2d flux spectra f(w,t) to 2d normalized spectra
remove spikes from data and replace with continuum
cross-correlate individual spectra in datablock against mean spectrum
construct templates for ccf
computes centroids of ccfs from 2d array
clean the data by removing outliers, fit and subtract low frequency background.
