EPIC Matlab flight data analysis software

Chris Bretherton, 11 Sep 01.

Requires the cdf flight file and a file like rf03_legs.dat, with the
beginning and end times (hhmmss) of each leg, and its classification
(1=dn sounding, 2 = up snd, 3 = 100' leg, 4 = 5000' leg, 5 = 100' x-wind
The analysis scripts are:

profiles:  Panels of profiles or cross-section of any field, or 
           low-pass variance of that field (prepend 'var' to field name).

flx_legs:  Low-leg bulk latent, sensible heat fluxes (plus air temp, SST,
           qv, wind speed)...easily modifiable to do other low-level
           avg plots.

rad_legs:  Radiative fluxes and LW flux divergence at lo, hi legs

pres_legs: Sea-level and 1600 m pressure, using GPS to hydrostatically correct 
           upper level pressure to the reference height.

Note allowable variables are in the file vars:
UI,VI,WI = winds, ATX,MR = T[C], qv[g/kg], etc.
