LSLambdaFunction2 (LocalSolver 12.5 API)

```
public interface LSLambdaFunction2
```
Lambda function interface. This particular interface is used to instantiate LSOperator.LambdaFunction in LocalSolver. A lambda function is a particular LSExpression composed of two parts:
- The arguments of the function (which are also LSExpression of type LSOperator.Argument.
- The body of the function. The body is an LSExpression that will be used to evaluate the result of the function. The body can be any LSExpression composed of any operands and operators supported by LocalSolver.

  - call
```
LSExpression call(LSExpression a,
                  LSExpression b)
```
    Evaluates and returns the body of the function. This particular method will be called by LSModel.createLambdaFunction(localsolver.LSLambdaFunction2) with two LSOperator.Argument. Your implementation must return an LSExpression that will be used as the body of your LocalSolver function.
