ConditionalExpression (Commons EL 1.0.1-SNAPSHOT API)

```
public class ConditionalExpression
extends Expression
```
Represents a conditional expression. I've decided not to produce an abstract base "TernaryOperatorExpression" class since (a) future ternary operators are unlikely and (b) it's not clear that there would be a meaningful way to abstract them. (For instance, would they all be right- associative? Would they all have two fixed operator symbols?)
