errors in the matlab binding

[stoianov]

Hello,
using ML ver 8.5 (R2015a), the required python packages in requirements.txt (python 2.7), there are errors in few calls:
(1) client.env_monitor_start(instance_id, outdir, true);
(2) client.env_monitor_close(instance_id);
(3) client.upload
(see bellow for details).
Could you please provide indications or update the code, also to work with the latest python packages.

I think there is some incompatibility with the "webwrite" matlab function; by now I "resolved" this with catching and ignoring the error in the outermost script (example_agent), and it seems to work, but I'm not sure this is a good solution.

Thanks, Ivilin
