linked list, ranges

[Joel Christensen]

Thanks again for the reply Jonathan. I'm using doublely linked list I 
made for a game where ships and there lazer bolts are in the same list. 
Without linked list I couldn't do things like create a lazer bolt or 
remove one while trans-versing the linked list. I had to use my own 
linked list, having a next and prev node in each object that goes in the 
list.
