    Returns the root of the node, the Token that indicates it's type. Returns null if there is no root (usually only if the node is a placeholder of some kind -- see isEmpty()).
  - public boolean isAnExpression()
    
    Returns true if the node is a complete expression.
  - public boolean isEmpty()
    
    Returns true if the node is completely empty (no root, even).
  - public void markAsExpression()
    
    Marks the node a complete expression.
  - public static Reduction newContainer()
    
    Creates a new Reduction with Token.NULL as it's root.
  - public CSTNode remove(int index)
    
    Removes a node from the Reduction. You cannot remove the root node (index 0).
  - public CSTNode set(int index, CSTNode element)
    
    Sets an element in at the specified index.
  - public int size()
    
    Returns the number of elements in the node.
