Detailed Description

This represents a cube in a project-based GUI interface.

The actual cube doesn't have to be open. This encapsulates ideas about an image such as it's footprint, it's cube, how it should be viewed, where it is on disk, etc. This class is designed to be semi-light weight - we should be able to have tens of thousands of these in memory without any issues (provided the Cube files aren't open - see closeCube()).
