Set Relation Names in Expression Tree

In class you will complete the following method from RANode.java:

public void setRelationNames(AtomicInteger globalInt) {
  // set unique relation names for every interior node in the tree
  // public String relationName; 
  // Interior nodes name is tempN; Leaf nodes name is relation name

}

Here is the documentation for AtomicInteger: AtomicInteger. In particular, you will use the second constructor to initialize the object, and the methods: get() and set() to manipulate the AtomicInteger. You can test this method by commenting out the calls to other methods in RA.java and printing the expression tree after setting the relation names.
