Making good headway!

Today the Entity Graph for the engine has officially been implemented... well... almost. I plan to make a special container class to replace the STL vectors that I am currently using to contain children entities. I should be able to get really good performance because it will basically be a singly linked list with all the crap stripped out, leaving only bare functionality to walk the list. I'll probably do that sometime next week, but for now, the vectors are working fine.
