##Traversal Tree Forest Algorithm able to load a forest of trees and traverse them.

Able to build, in a recursive way, a non-binary forest of trees where each node has a link to the left most child and a right link to the right most sibling.

A new node could be ** a child or a sibling of the current node so it is added at the first call ** a child or a sibling of another node so it is added at the next first recursive calls.

First part is checking if the new node has to be a child, the second part if it has to be a sibling. Pre-condition: the parent must exists.

The exit condition from the recursion is the call to the new operator and the return of the new node.

Many tests implement some use cases to provide the working condition of the data structure and how it is traversed to collect or visit all the existing nodes.
