Completed the backporting of fortran 90 code to NCL. All routines should now pass numpy views directly to fortran to be filled rather than copying.

+!     uses the midpoint between the pressures of the vertical grid
+!     points as the bounding levels.  The array only contains mkzh
+!     levels, so the pressure of the top of the uppermost layer is
+!     actually excluded.  The kth value of pf is the lower bounding
+!     pressure for the layer represented by kth data level.  At the
+!     lower bounding level of the lowest model layer, it uses the
+!     surface pressure, unless the data set is pressure-level data, in
+!     which case it assumes the lower bounding pressure level is as far
+!     below the lowest vertical level as the upper bounding pressure
+!     level is above.

+! !IROUTINE: capecalc3d -- Calculate CAPE and CIN
+!
+! !DESCRIPTION:
+!
+!   If i3dflag=1, this routine calculates CAPE and CIN (in m**2/s**2,
+!   or J/kg) for every grid point in the entire 3D domain (treating
+!   each grid point as a parcel).  If i3dflag=0, then it
+!   calculates CAPE and CIN only for the parcel with max theta-e in
+!   the column, (i.e. something akin to Colman's MCAPE).  By "parcel",
+!   we mean a 500-m deep parcel, with actual temperature and moisture
+!   averaged over that depth.
+!
+!   In the case of i3dflag=0,
+!   CAPE and CIN are 2D fields that are placed in the k=mkzh slabs of
+!   the cape and cin arrays.  Also, if i3dflag=0, LCL and LFC heights
+!   are put in the k=mkzh-1 and k=mkzh-2 slabs of the cin array.
+!
+
+
+! Important!  The z-indexes must be arranged so that mkzh (max z-index) is the
+! surface pressure.  So, pressure must be ordered in ascending order before
+! calling this routine.  Other variables must be ordered the same (p,tk,q,z).
+
+! Also, be advised that missing data values are not checked during the computation.
+! Also also, Pressure must be hPa
