%EXPORT_CSV Export grid and data in CSV format.
%
%   EXPORT_CSV( FILENAME, FEA, EXPR, SOLNUM, FID_LOG )
%
%   Export of grid points and corresponding solution/expression data
%   in CSV format. The CSV file will consist of a header line with the
%   space coordinate names, dependent variable names, and given
%   expressions (columns). This is followed by the actual data rows
%   where one line corresponds to the data for the specific grid
%   point.
%
%   FILENAME gives the output file name. FEA must be a valid FEA data
%   struct, EXPR is optionally a cell array with expressions to
%   process (the grid coordinates and dependent variables in the FEA
%   struct will be prepended to EXPR). SOLNUM is optionally the
%   solution number of which to evaluate the expressions. FID_LOG is
%   an optional log file handle for message output (negative for gui
%   output or empty for no output).
