This is a feature request for an adverse command to pushBack
Potential use:
_arr = [1,2,3,4,5,1]
_arr pullBack 4; //_arr = [1,2,3,5,1]
_arr pullBack 1; //_arr = [2,3,4,5]
Potentially can add something akin to pullBackUnique to differentiate between "//removing one matching element from the array//" and "//removing ***all*** matching elements from the array//"
