5f7138c300 BUGFIX: Partial implementation of chosen name attacks could yield false type flaw attacks. 
For the typed model, this was not an issue.

66e18deb3f NEW: Added claims: Commit and Running. 
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.

9624c49885 Disable some aggressive error reporting: unclear why this is actually invalid per se 
in the presence of agent name variables (role names) with non-basic typing.

5ffe3d2752 Added more verbosity to some parts with -v switch. 
In particular, verbose ('-v', '--verbose') now lists protocols with their correct
claims, and also the protocols without such correct claims.

6cd8007ab0 EFFICIENCY: New (default) heuristic. 
Given that sk/pk/k are now hardcoded, we can exploit their occurrences with this
new heuristic.

The heuristic can now scan for the lowest term depth at which either sk or k occur.
This will cause the heuristic to favor looking for sk, then sk(x), and only later
other terms. In a small test this was twice as fast. For protocols based on pk only
the performance loss should be negligible.

The old heuristic was 162, now it is 162+512 = 674.

e42aa1215e Scyther.py: Added Caching to Scyther's Python interface. 
Cached data is stored in:

Cache/XX/YYYYY.out (stdout)
Cache/XX/YYYYY.err (stderr)

Where XX^YYYYY is the sha256 hexdigest of the concatenation of the input spdl and
the arguments.
