Added boilerplate for Basic Examples

For basic examples, could a format similar to that typically used in [blocks](http://bl.ocks.org/mbostock) be useful? It could reduce the boilerplate code and allow one to focus on the important code for the component? Maybe something like this:

```html
<!DOCTYPE html>
<meta charset="utf-8">
<title>D3 Financial Components, A Component's Example - Scott Logic</title>
<style>
/* Chart/component styles... */
</style>
<body>
<div id="chart"></div>
<script src="http://d3js.org/d3.v3.min.js"></script>
<script>
/* Demonstrate usage of the component... */
</script>
```
