It still doesn't remove the need for a remove
function. Also, you can just call delete for the .all
array since its associative, but the children array is
ordinal, so you could slim down the removeFromArray to
only work for ordinal arrays and the associative array
can be deleted using the delete function. However, I
do not see that this would provide to much of a speed
boost though because I don't believe that associative
arrays go through a loop inside the removeFromArray
function.
