============================== Instruction ==============================

FamilyTreeJS is very easy to use. Of course, the first step is to include
the Javascript file in the <head/> section of your HTML document.

After familytree.js has been included you include the code to build your own
family tree . You will need to wrap your code in some way to prevent its
execution until after the DOM has loaded. For example, with jQuery you would
wrap your family tree code with:

$(document).ready(function() {
	// [ ... you code here ... ]
});



** Example:

  var tree = new FamilyTreeJS.FamilyTree();
  var chandler = tree.AddPerson('Chandler');
  var moriah = tree.AddPerson('Moriah');
  chandler.birth('Roan', {partner: moriah});
  tree.Render(document.getElementById('dom_element'));

This will generate a tree showing Chandler and Moriah having a child named Roan.
Any person on the tree who does not have a parent should be added by tree.AddPerson().

To avoid having to instantiate a variable for each person in the tree you
can chain any number of births together:

  var roan = tree.AddPerson('Robert').
  	birth('Allen').
  	birth('Chandler').
  	birth('Roan');

Obviously this is a pretty boring family tree. There is nothing defining
any of the mothers. It is simple to add them in, however.

  var roan = tree.AddPerson('Robert').
  	birth('Allen', {partner: tree.AddPerson('Arlene')}).
  	birth('Chandler', {partner: tree.AddPerson('Leslie')}).
  	birth('Roan', {partner: tree.AddPerson('Roan')});

Admittedly this syntax is a little confusing because, at first glance, it's easy
to think Chandler was born to Allen and Arlene when his parents are
actually Allen and Leslie. It just takes getting used to.

Those are some simple trees, now for something a bit
more complex: joining two branches.

  var tree = new FamilyTreeJS.FamilyTree();
  
  var henry_i = tree.AddPerson('Robert the 1st').
  	birth('William the Conqueror').
  	birth('Henry the 1st');
  	
  var edith = tree.AddPerson('Duncan the 1st').
    birth('Malcolm the 3rd').
    birth('Edith');
    
  var matilda = henry_i.birth('Matilda', {partner: edith});
