 The problem is given now, let us search for a solution with `HerbSearch`. For now we will just use the default parameters searching for a satisfying program over the grammar, given the problem and a starting symbol using

 Eventually, we want to test our solution on some other inputs using `HerbInterpret`. We transform our grammar `g` to a Julia expression with `Symboltable(g)`, add our solution and the input, assigning the value `6` to the variable `x`.
