+%STRUC2CELL recursively converts a structure into a cell
+%   
+%   EXAMPLE: 
+%
+%     Define structure:
+%       p = [];
+%       p.verbose_level = 2;
+%       p.energy = 6.2;
+%       p.engines.engine0.name = 'DM';
+%       p.engines.engine0.iter = 200;
+%       
+%     Convert to cell:
+%       fn = struc2cell(p)
+%
+%     Output:
+%        1×4 cell array
+%           'verbose_level'  'energy'  'engines.engine0.name'  'engines.engine0.iter'
