MATLAB Repo Comment Stripper

The package includes two functions:
-striprepo which deletes all or specified comments from a Git repository, e.g. you can delete comments that start with '%?', '%TODO:' or any other sequence
-stripfile which does the same but affects a given file or creates a modified copy
Block comments are affected this way:
%{
<any string>
comment content
%}
Check out README.md on GitHub for more detailed description.
