Detailed Description

Provide a LIFO stack implementation. Internally, this is based on an ArrayList.

You may push null references onto the stack, but you must exercise caution when using the peekFirst method; it returns null to indicate when the stack is empty.

This could readily be replaced by java.util.Dequeue<T> once we move to Java 1.6.
