A trivial bug. A typo in loadData. On line 81.

As I described in the issue I raised - Line 81 in loadData.m uses the incorrect quote mark, which then means the %s doesn't work as intended and instead comments out the rest of the line resulting in a script failure and this then causes testpmtk3.m to ask you to check internet connection or perl installation.

    fprintf("%s exists, no need to download",dest);

should be:

    fprintf('%s exists, no need to download',dest);

That fixed the problem for me. So I have submitted this pull request.

Sorry if this isn't the correct way to do this - I'm kind of new.

Many thanks,

Alexander.
