Create 'Hello EZOut' duck type / formatter

[StartAutomating]

As example formatting will soon be isolated into it's own module (#127), some newer, simpler examples should take its place.

We can do this by creating a duck type equivalent to hello world.

Aka, create a hashtable like:

[PSCustomObject]@{PSTypeName='Hello.EZOut'}

And allowing it to have a formatter which display a message, as well as a script property and some script methods to manipulate the message content.
