Hero digger

Of course, digging will be allowed in any town. There will also be an emergency stop.
And why should the manual be called from within the program itself? For convenience? This is no longer a manual, but a description.

I have already added another nice feature: a file is created with statistics on excavations. It will look something like this:
Hero1 Warlock 8 Centaur 0 Gargoyle
Hero2 Knight 30 Peasant 0 Archer
Hero3 Warlock 7 Centaur 4 Gargoyle
Hero4 Knight 30 Peasant 0 Archer
Hero5 Sorceress 19 Fairy 3 Gnome
Hero6 Warlock 8 Centaur 0 Gargoyle
Hero7 Sorceress 18 Fairy 0 Gnome
Hero8 Knight 46 Peasant 5 Archer
Hero9 Knight 48 Peasant 5 Archer
Hero10 Warlock 6 Centaur 3 Gargoyle
