enumerations and events cause premature end of m-file parsing

[goszpeti]

If an m-file class contains enumerations and events, the file parsing will end at that declaration.
example code:

class myclass

enumeration 
MYENUM
end

function myfunc()
end
end

myfunc() will not be parsed.
I already found the culprit for this in mat_types.py at lines 964 and 974 (version 0.34).
idx is not increased after exiting the while loop, so the next end will be considered as the class definitions end.

Thanks for the detailed report, it was very easy to find the error.

Fixed in version 0.3.5 (https://github.com/sphinx-contrib/matlabdomain/releases/tag/0.3.5)
