Ok...I will definitely look into this later tonight.

I have read in several places that using return_internal_reference is a bad 
idea. I am already using it in several places. I don't expect to have any 
issues with invalid references to objects in a container.

Is there anything else I should watch out when using 
return_internal_reference? Would you recommend that I use shared_ptr's 
instead?
