Log message:
	A full scan on the user-manual portion of the introduction.
	In particular:
	- added a proposition after Minkowsky's theorem for rational polyhedra;
	- preferring the use of \lambda wrt \mu for scalars;
	- yet another variation on the definition of extreme rays;
	- "non-negative" combinations are now "positive" combinations;
	- better explaining the border-line cases of the generators representation.
