%EXPORT_XLS Export grid and data in Excel format.
%
%   EXPORT_XLS( FILENAME, FEA, EXPR, SOLNUM, FID_LOG )
%
%   Export of grid points and corresponding solution/expression data
%   in Excel format. The output 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).
