Detailed Description

Simple stack implementation that keeps the back() cached locally for fast access rather than at the back of the vector which is the traditional stack implementation.

A conventional std::vector<> stores the rest of the stack. Although fast_back_stack contains a stl container it only implements the back push_back(),pop_back() and back() methods so is not as general purpose as stl stack implementation. The focus of the fast_back_stack is purely to maximize the speed at which the back can be accessed.
