Log message:
	There are now three flavours of grid widening.
	
	The `generator_widening_assign()' is as commited previously
	(using generators) and file `widening2.cc' tests this.
	
	The `congruence_widening_assign()' is a renaming of the old
	`widening_assign()' (using congruences) and `widening1.cc' tests this.
	
	The new `widening_assign()' uses either of the above two widenings
	depending on which of the systems describing the grid are
	up-to-date. The new test file `widening3.cc' tests this widening.
	
	There are, similarly, three flavours of a
	`limited_*extrapolation_assign()' operator.
	
	The documentation in `definitions.dox' on the grid widening
	has been brought up to date and improved.
