allow to open multiple data overlays using url GET param

originally asked by Andrei.Zinovyev@curie.fr:

However, my question is - can we automate it further? What I want to do is to 1) open browser with minerva project, 2) remotely activate the overlay such that it would be displayed without any intervention from the user.

In other words, I would like to write a small external javascript program which would send an overlay to a dedicated minerva server, open browser and show the visualization, all without requiring intervention from the user. Is it possible with current minerva API functionality?
