Just experimenting with publishing a package

var makeTree = function(){
  var newTree = {};
  newTree.value = undefined;
  newTree.parent = null;
  newTree.children = [];

  _.extend(newTree, treeMethods);
  return newTree;
};

var treeMethods = {};

treeMethods.addChild = function(val){
  var child = makeTree();
  child.value = val;
  this.children.push(child);
  child.parent = this;
};

treeMethods.contains = function(val){
  var found = false;
  _.each(this.children, function(child){
    child.value === val && (found = true);
  });

treeMethods.removeFromParent = function(i){
    this.children[i].parent = null;
    this.children.splice(i,1);
  };

  return found;
};
