PyTelluric and Filter

- PyTelluric is an automated telluric-correction script written in
Python inspired by the telluric removal IDL-based code of Matheson et
al.
- A few kinks still to be worked out for PyTelluric:
1. 6250 ("C") band needs to be corrected in a better fashion. Some
standard stars appear to not have this band resolved sufficiently.
2. Algorithm works for SN2012cg and SN2013ex. Need to test it on
SN2012fr and SN2013aa, and perhaps others (with their own standards).
3. Might be worth expanding the number of data points in the science and
standard star data NumPy arrays before cross-correlating.
4. Add feature to shift science spectrum based on cross-correlating
science sky spectrum vs. master sky.
- PyTelluric has been implemented into the pipeline via the new function
telluricCorrect()
- New function cleanCombinedSpectra() interpolates over leftover chip
gaps and highly deviant pixels (leftover cosmic rays or background
oversubtraction) in the combined science and standard star spectrum.
- There is typically one leftover chip gap at the reddest setting when
an even number of spectra are od-combined. There are typically very few
highly deviant pixels interpolated/smoothed over.
- indivtasks(), pipehistory(), and dictionaries() updated accordingly.
