Major update that includes octave files

1) Created new subdirectories for octave files that handle AERI
reprocessing.

2) Update to paeri_reprocessing.py, BUT this has been superseded by the
use of aeri.py, which contains a Class called REPROCESS.  See aeri.py.
Two major class additions: PAR and REPROCESS

1) PAR reads an AERI parameter (par) file for a given day.

2) REPROCESS contains several functions for reprocessing AERI data:
__init__ - initializes a REPROCESS instance, setDirectories - general
utility used by other functions, retrieveDataFromNOAA - title says it
all, NLAPP - performs nonlinearity correction on AERI data, QC -
performs quality control (QC) on AERI data, and AERICAL - performs AERI
calibration in several steps.
