matrevis 6a1e30b0a2 - Reconstructed step forward. There is still some visible bug in the
imlpementation, so this version should not be considered definitive.
please give me an other day to check it.

elvez 48fc2f5a00 - Added still more error checking to PythonCPUPolicy. But the code which calls its methods should be updated to handle the new exceptions...
- Added a base class for cpu policy exceptions to make simpler their catching
- Implemented all numeric fields in dialogs with spinboxes, with bounds checking

matrevis d72ce96508 - Corrected a bug in step forward, which was incorrectly assuming
that the size of the history was the coordinate of the instant
  to add.
- Corrected a bug in step forward, which was incorrectly assuming
  that all processes started at instant 0.
- Added a wizard to show a bug in step forward, which thinks that
  the simulation is terminated while it isn't since some processes
  are still future.
- Commented some unused code in step forward (extendThread()).
- Still to extract methods from Extender and provide them to 
  step forward in a more suitable (static) way.

matrevis 574723a35b - Added full request support, altough still not working
at all. Compiles and runs, but the output is not
  correct. Anyway, now it is just a matter of logics :P
- Corrected some minor bugs in step forward.
- Step forward is now rather messy, but still better than
  four hours ago.. altough this can be hard to believe.
- Added some wizards that help finding bugs.
- Rewritten dyn process get_state as it was guilty of
  premature optimization :)

matrevis efe7dedd61 - Request queues are now correctly managed by the ConcreteEnvironment
copy constructor and by the add_resource and remove_resource methods
  found in ConcreteHistory.
- Scheduler now adds the requests in the queue when appropriate, and
  removes them when exhausted.
- Still to implement the management of the state of requests depending
  on their position in the queue
- Still to implement the way threads block depending on the state of
  their requests
- step_forward now reuses some bunch of code taken from the prototype

set_notify_enabled(false) before starting)

adjustement / resizing problems (they're not easy to work out 
correctly).

matrevis 96055b4cf1 - minor bugfix: scheduler was terminating subrequests before decreasing
their elapsed time
- requests are now behaving nicely, since they are raised at the correct
  instant, and terminated at the right instant
- the ready queues are still not ready, tough :(, anyway, now there is
  really nothing else to do before them.
- stepforward is looking much more uglier (if possible).

matrevis 56a7ce1221 fixed a bug involving scheduler keeping a running thread in the ready queue
when that thread had just been given the cpu.
fixed a bug involving text-simulation displaying the wrong timestamp for
each snaphot. Now the first snapshot printed is correctly tagged "-1".

added (for the sake of lazyness) a method to readyqueue letting anyone
delete the first element on the queue. Not having this would imply
rebuilding the whole queue each time a thread was selected to run.

Small commits avoid complex mergings.

tchernobog c6ebe792e4 - Make Scheduler::step_forward return a bool representing if
the step went okay or otherwise if the simulation ended
- Fix simulation states in concrete_simulation.cc
- Manage end of input (now CTRL+D exits the program, and 
you can redirect a file in input knowing that at EOF
sgpemv2 will terminate)
- Fix a bug in Scheduler that didn't add the newly created
environment to History when the simulation ended, thus leading
both to a memory leak and an inconsistency in representing
the simulation
