Initialized Git Repo
Fixed .pro so it works both on Linux & Windows
f_inf & f_sup were not created when clicking on "Draw F"
Renamed some event handlers, removed some unused instances
Removed one more unused Sivia instance
Removed 1 useless call to SIVIA by using union and intersections on contractors instead.
Removed 1 useless Sivia constructor (the one without the box parameter)
Changed the way to get epsilon: now SIVIA doesn't sometimes go in an infinite loop
Changed the window name. The software now just works as long as you don't try to solve problems with a too little epsilon.
