Updating the experiment toolkit to work with the new .zip file

[yehudarav]

Experiment toolkit
In the current version, the toolkit downloads the experiment description from argosWeb and creates its version of json.
However, in the new version of argosWeb, we download the whole experiment into a .zip file.

we now add a new factory that will load the .zip file and create the objects wrapper.
The new version will also support:

Groups of devices
Logs

Completed the first step, still does not include logs and groups of devices.
