1) log messages are now flushed. 2) very long computation times due to naive code to check for unused variables are now much shorter

[bug cavale 93] solved: issue when resetting a stateless node. Now generating a warning and forcing the stateful status. Could be improved to remove the reset statement. (TODO)

- Bugs in partial evaluation for equalities among bool constants
  and a nice recursive call generating a stack overflow! Now solved
- Setup a timeout for z3 in seal
- Better log for seal

Contract resolution still need to be done as well as dealing with the machine code level and so on.

- Modules now is more integrated and performed the building of the type/clock env.
  previously some computation were performed twice by different functions. Some of these functions have been moved from compiler_common to modules

- Adapted the parsing of specification with a cocospec compatible one
- The data structure of contracts is now almost cocospec compatible
- Lustrec-test has been updated to use the newest syntax

Adapted the parser/types/constructors for cocospec syntax
