Count (Starjava TOPCAT API)

java.lang.Object
- uk.ac.starlink.topcat.Count

```
public abstract class Count
extends java.lang.Object
```
Utility class for handling positive integers. Useful if you want to reference many instances of small values, and not so many of large ones; this implementation caches the small ones, and creates the large ones on demand.
