ICalculator (Nebula NatTable 2.0.0-SNAPSHOT API)

```
public interface ICalculator
```
Interface that is used by the CalculatedValueCache to calculate values in a background process. In a modern world this would be better implemented as a function/lambda, but as we need to work with Java 6, there are no lambdas yet and so we need to work with anonymous inner classes.
