Add examples of iteration patterns for primitive Stack to reference guide

[donraab]

The new reference guide is now in Asciidoc. The relevant section is now here: https://github.com/eclipse/eclipse-collections/blob/master/docs/2-Collection_Containers.adoc#primitive-stacks

Use the Lost and Found Kata as a guide for the iteration patterns that can be included for various primitive types.
