Simulation progress indicator

[ssadjina]

At least for some cases, the progress indicator during a simulation gives strange results. More precisely, it never reaches the final "95%" mark and, instead:

This particular example was obtained with the following execution config file:
start 0 stop 8 step_size 1 comm_timeout_ms 100000 step_timeout_multiplier 1000 instantiation_timeout_ms 60000

In this example, this behavior is experienced up a total simulation time of 20s (again, with step size 1s):
start 0 stop 20 step_size 1

Scaling all the times by a factor of 0.1, however, causes the progress indicator to function as expected:
start 0 stop 2 step_size 0.1

I suspect a minor error in the caclulation of the progress indicator.

I seem to have missed my chance to assign correct labels for this issue. Be gentle, this is my first trip to GitHub ;)

For future reference, this is already registered in our old issue tracker as VIPROMA-118, with the following description:

[coralmaster] always prints its progress in increments of 5%. If the total number of time steps in a simulation is less than 20, this has the unfortunate consequence that 100% is never reached. The solution is to do something a bit more clever to the nextPerc variable in [src/master/main.cpp] than simply add 0.05 to it.

Thanks for posting it here! Label added. ;-)
