Footprint (SpotBugs 4.2.0 API)

java.lang.Object
- edu.umd.cs.findbugs.Footprint

```
public class Footprint
extends java.lang.Object
```
Class to maintain a snapshot of a processes's time and memory usage. This uses some JDK 1.5 APIs so must be careful that it doesn't cause any harm when run from 1.4.
