a03f06ea41 BUGFIX: Auto-claim naming scheme was context dependent. 
The automatic mechanism to assign labels to claims was dependent on the
context. In practice, a claim could get a different label when analyzed in
isolation compared to when analyzed in parallel with some other protocols. This
caused problems for the multi-protocol analysis.

7d584cca1e Added GPL 2 License to the C sources. 
A first step towards releasing Scyther completely to the public.

1ce03104c5 Major: 
- Added rho/sigma/constants fields to the runs, on which the new code is
  based. Over time, .locals should be deprecated in favour of these
  better variants.
- Untyped variant is out of grace for the time being (cf. Athena interm
  problems)
- Improved graph output further.

Minor:
- Added TERMLISTADD and APPEND macros for more concise code.

5487d3ae90 - From this version onwards, Scyther no longer supports the modelchecker 
method. A big cleanup has been started, but is not finished yet, so
  minor artefacts might still remain. These are to be cleaned up later.

00616e45ed - Bit masking was incorrect: & binds less strong than == ! 
This caused many of the --experimental switches not to work.

Stuff seems to be working again, slightly less efficient though (count
  states).

bb7259a1ad - Removed some too interesting pruning methods that really need theorems 
first. Revealed by the certified e-mail protocol by Abadi and
  Blanchet.

0505aaacd6 - New claim: CLAIM_Reachable 
- 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)

the role names.

cee11bc0af - Extra checks: 
* For incomplete protocols, better handling of dangling labels.
  * For termSubTerm better handling of NULL cases.

f22ce0dcb9 - Big change in the Arachne algorithm: decryptor sequences now get 
expanded explicitly. This solves a long-standing issue with {k}k
  decryption to yield k. Needs some testing to ensure that it did not
  introduce any new errors.

9271cc7624 - Matching method propagation was wrong in new switch code. 
- Some fixes for protocols that do not include matching send/read
  combo's. In particular, the max encryption level method ranged over
  the sends; now over all events. Maybe it can range over read events
  only?

TermOp1(t)). Renamed all uses.

0de3320009 - Fixed a memory leak in termLocal. This did not cause any problems for 
the modelchecker, as it calls it only once, but it caused major
  problems for the arachne engine, which creates and destroys semiruns
  all the time.

d58fc5ab43 - Made the label naming unique, by adding tuple info with the protocol 
name. Now, we can simply test multiple protocol names by
  concatenation.
- Removed the pointer equality leaf hypothesis, as it didn't hold
  anymore.
