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.

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

- Fixed all Dynamic and Static entities lacking proper destructors:
Dynamic entities need to delete Dynamic children, Static entities
need only to delete them from the list of their siblings
- Added methods to get Static "core" from Dynamic*.
- Now get_core() is a pure virtual function into DynamicSchedulable.
A quite nice solution(?), really, if I can say that myself... ;-)
- ConcreteHistory is half-implemented. It's the other half that
worries me.
- TODO: finish off ConcreteHistory, and check that things get destroyed
properly (no leaks allowed, use valgrind).
- TODO: rework Simulation
- TODO: Scheduler rewrite
- *A side note*: this code is becoming a mess. I prefer references over
pointers, but someone other prefer pointers over references, and what
happens is that you've to continously pass from one to another when
invoking other methods... this is bad.
