copernicus system v.0.0.1

Basic astro-physics system. For a quick-start run copernicus.sh script.

On startup the solar.script is loaded (you can modify it freely and
watch the changes).

Also under OpenGL Canvas you can see a command line into which you can
write any predefined commands (all of which are used in solar.script).
They should be self-explanatory with few pointers - mass is expressed in
kgs, distance in kms. Object's radius is tranlated through decimal
logarithm (for the sake of clear presentation).

Enjoy!
