AWS EC2 Image Retrieve Version 1

The describe_images function is the base AWS::EC2 gem call we are using for this handler and returns a multi-level hash/array nest with a top level hash key of "imagesSet".

The imagesSet has the following pseudo-xml form. Elements with the tag are array members and are referenced by numerical index.

All others are hash members and are references by element/key name.

To retrieve the imageId, for example, simply flatten the above structure by removing inapplicable items

Treat items as arrays and all other members as hash keys. Doing so, we can reference imageId value in the following manner:

@baseawsobject.imagesSet.item[index].imageId

In this handler, we are returning just the more interesting properties for an instance. Future versions may incorporate additional properties.
