Writing Magento Modules

All custom modules should have a Namespace and Module Name. These are used below as {Namespace} and {Module}.

Caution: The Magento autoloader is known to have problems with CamelCase namespaces and/or modules between Windows and *nix systems. If your module requires more than one word for either of these, it is best to just concatenate them to avoid any issues (Example: {Namespace}_{Examplemodule}).

Points for investigation

Generate high-level overview of all the main components
How are the total item counts for each option generated?
How is the catalog updated to display the matching products?
How are options rendered?
What are the customisation points?
What events are dispatched?

	/* To use this example:
	1. Download this html file
	2. Replace the form action url with your own from the MailChimp supplied embed code
	3. Within the action url, replace "subscribe/post" with "subscribe/post-json"
	4. Be sure the action url starts with http://. If it doesn't, the form will hang when testing the html as a local file in your browser.
	5. Open this file in a browser on your local machine
