Rewrite of Program Fixpoint to overcome the previous limitations:
- The measure can now refer to all the formal arguments
- The recursive calls can make all the arguments vary as well
- Generalized to any relation and measure (new syntax {measure m on R})
This relies on an automatic curryfication transformation, the real
fixpoint combinator is working on a sigma type of the arguments.
Reduces to the previous impl in case only one argument is involved.
The patch also introduces a new flag on implicit arguments that says if
the argument has to be infered (default) or can be turned into a
subgoal/obligation. Comes with a test-suite file.
