scan4errors

Scans folders for Matlab files that have MLINT errors and warnings

% SCAN4ERRORS searches the current directory (recursively) for Matlab .m files with code errors/warnings (mlint)
%
% errors = scan4errors(files) searches the FILES structure created by a "dir" command and returns all detected errors. Warnings are ignored. If not
% provided (or empty), FILES will use the current working directory. By default, only errors (i.e. red MLINT) will be returned in the ERRORS structure.
%
% errors = scan4errors(files,severity) allows the user to define the severity of errors and warnings that are returned. The default is "errors" meaning
% that only error messages will be returned (i.e. red MLINT). "Severe" may be used to return both errors and severe warnings, and "all" will return
% all errors and warnings. Argument is case-insensitive.
