we need to move the "continous/non-continous" code snippet out of ConcreteSimulation
and into TextualSimulation/the GUI Simulation. In fact, ConcreteSimulation
is just a state machine that performs a single step and then puts itself
either in paused state (if the Simulation hasn't finished) or into stopped state
(if it finished)

with a *factor* of ~640x480. That means ~64*48*10^6*3 bytes = a ~1.1 Gb RAM pixmap.
The problem didn't show in versions of cairo >= 1.2 because it automagically
clips (yeah, cairo programmers *are* smart :-))
It is temporary fixed for the moment, will be made better asap.

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.

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 :)

- 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

- Add History::set_notify_enabled() for usage by the frontend

set_notify_enabled(false) before starting)

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).

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.

- 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)

environment to History when the simulation ended, thus leading
both to a memory leak and an inconsistency in representing
the simulation
