first attempt at location zombie spawning

build location array on server start to store vars cause locastions var
storing is fucked - store vars
find location closest to player - find in array, get var numZombies
spawn zeds from location, over radius *
on despawn, check for closest location and setvar that obj in array
* to do - set radius on building object and check it
* test location array data
* perhaps try with all locations? so zeds spawn from everywhere, and we
can use nearestLocation instead of nearestLocations - or maybe some
other solution
* test CPU intesivity
* test MP transmission of var - net usage
