Destruction behaviour modifiers

User can decide how destruction happens, setting global variables

//Destroy policy: destroy and kill aliens if and only if the city is invaded by exactly 2 aliens
var strictTwoAliensDestroyPolicy bool = false

//true: will "clean" the map just after landing, destroying cities invaded by two (strict = true)
//or more (strict = false) aliens. After t0 you'll have at most one alien per city. Will they still exist?
//Does not care about Destroy policy
var doIwantFightsAtT0 bool = false

//true: enable kills and destruction only at the end of the turn/step so after all the aliens that 
//survived the previous step move, if not trapped alone and if killing policy is respected.
//false: when an alien arrives in a city, could find one or more aliens already there.
//Would kill and destroy during the step, as soon as the alien arrives in the city. 
//If aliens don't move, don't kill. Must respect the destroy policy
var killAndDestroyAtTheEndOfStep bool = false

TO DO
