Add some custom templates

[bobbingwide]

Certain pages and posts need to support the ability to display content full width.
Others need to display a tall featured image to the left of the main content
and I also need to be able to demonstrate other custom templates

Here's how WordPress searches for a template for the "page" post type.

Template name format	Example template name	Sample	Usage
$custom	featured-image-left	navigation-component	Use for a tall narrow featured image
page-$slug	page-template-hierarchy	template-hierarchy	Use for a full width featured image
page-$ID	page-2	page-2	Demonstrate page template matching ID
page	page	Any other page
singular	singular	Any other single content	eg custom post type
index	index

Such as the output-input template implemented in Fizzie to demonstrate a method of debugging template parts and/or post content.

Here's an interesting side-effect of the custom CSS in the output-input custom template part.
Notice all the dotted red borders.
Perhaps the CSS needs to be made a little more specific.
