Tutorial demo scene

A new demo is provided with the last release, starring Andy the robot, and some video tutorials too (in French, but with English subtitles) explaining step by step how to re-create this scene by yourself.

Those video tutorials gives an OpenSpace3D overview in a nutshell, and were wrote to accelerate familiarisation of new users with the tool.

All your questions relative to those tutorials can be posted on the forum.
