Matlab frontend, documentation and build instruction for

processgrid mex script.

This interface allows users of the Matlab Reservoir
Simulation Toolbox (MRST) to use the OPM corner point
grid processing in MRST.  This represent a significant speedup
over the native Matlab grid processing already avaliable in
MRST.

+function varargout = processgrid(varargin)
+%Compute grid topology and geometry from pillar grid description.
+%
+% SYNOPSIS:
+%   G = processGRDECL(grdecl)
+%
+% PARAMETERS:
+%   grdecl - Raw pillar grid structure, as defined by function
+%            'readGRDECL', with fields COORDS, ZCORN and, possibly, ACTNUM.
+%
+%
+% RETURNS:
+%   G      - Valid grid definition containing connectivity, cell
+%            geometry, face geometry and unique nodes.
+%
+% EXAMPLE:
+%   G = processgrid(readGRDECL('small.grdecl'));
+%   plotGrid(G); view(10,45);
+%
+% SEE ALSO:
+%   processGRDECL, readGRDECL, deactivateZeroPoro, removeCells.
