BoxEvaluation

java.lang.Object
- BoxEvaluation

```
public class BoxEvaluation
extends java.lang.Object
```
The static method evaluate() returns an instance of this class. The evaluate() method checks to see if the placement is legal, or if there's some other problem. If not, it counts the number of items, and the area of the items as well. Both are written into the public variables below. The fraction of allocated items can be requested through a call to getFracItems().
