Added files from coslib repository
re-organize cosview scripts
Pylint changes and working on flux-calibration for lightcurve
Attempting to add in an error estimate
Further improvements to flux-calibration of lightcurve
Error estimate is simple poissonian statistic, sqrt(N)
added printed progress bar for lightcurve extraction
Fixed bug in output times.  Set correct xlimits for each detector
added cos/misc.py with functions for re-makeing x1dsum from asn tables
If cannot import CALCOS, remake_asn won't be imported
pulled extraction from HDU out into separate function
pulled getting extraction locations into function
Added fluxcal function, started implementing multiple HDU extraction for both FUVA and FUVB combined extraction
Add extraction from multple FUV HDUs
get_flux_correction needed OPT_ELEM, etc passed in
missed case syntax in last commit
Re-factoring of lightcurve functions into lightcurve class.  Added convenience command-line script as well
initial commit of drift_align functions
Exclude stripe C for G230L data.  Print out more information
Added in extraction of background counts, subtraction of background, and changed error estimate
