Introduced a new event:
match(pattern,groundterm)
This event can only be executed if pattern can be matched to groundterm.
Variable substitutions are persistent with respect to later events in
the same role.
Currently implemented as syntactic sugar, essentially unfolded in role R to:
fresh x;
send ( R,R, { groundterm }x );
recv ( R,R, { pattern }x );
This work is not complete yet in the send that the output still contains
the unfolding. Ideally, the graph rendered detects this syntactic sugar
and renders a simplified event. This should be possible on the basis of
the label name prefix.

There are two new claims:
claim(X,Commit,t) : check for agreement on data
claim(X,Running,t) : signaling claim
The property checked is that each claim Commit needs to be preceded by a Running
with an identical term t.
Cherry-picked from commit 99a6be00e9d3d219ec73665607e8a3a7d65d04d1
- Added new switches:
-G,--generate-statespace
-C,--generate-claims
- Claims are now allowed to have no label (they will be generated
automatically)
- Output summary shows parameter of claims
- Internally, new symbols can now be generated by
symbolNextFree(prefixsymbol)
