Stack

The Stack class represents a last-in-first-out (LIFO) stack of objects. It extends class Vector with five operations that allow a vector to be treated as a stack. The usual push and pop operations are provided, as well as a method to peek at the top item on the stack, a method to test for whether the stack is empty, and a method to search the stack for an item and discover how far it is from the top.

When a stack is first created, it contains no items. @author paling

`function new(): Void`

Creates an empty Stack.

`function empty(): Bool`

Tests if this stack is empty.

returns true if and only if this stack contains no items; false otherwise.

`function peek(): Dynamic`

Looks at the object at the top of this stack without removing it from the stack.

returns

the object at the top of this stack (the last item of the Vector object). undefined is there is no items.

`function pop(): Dynamic`

Removes the object at the top of this stack and returns that object as the value of this function.

returns

The object at the top of this stack (the last item of the Vector object). undefined if there is no items.

`function push(item:Dynamic): Dynamic`

Pushes an item onto the top of this stack. This has exactly the same effect as:

append(item)

item	the item to be pushed onto this stack.
returns	the `item` argument.

`function search(o:Dynamic): Int`

Returns the 1-based position where an object is on this stack. If the object o occurs as an item in this stack, this method returns the distance from the top of the stack of the occurrence nearest the top of the stack; the topmost item on the stack is considered to be at distance 1. The equals method is used to compare o to the items in this stack.

o	the desired object.
returns	the 1-based position from the top of the stack where the object is located; the return value `-1` indicates that the object is not on the stack.
