Instead of passing a vector of boolean factors, pass a single expression (a conjunction). This prepares the way for more complex expressions, but no grammar changes are made here. The expression is stored as optional, since we'll need a way to indicate whether an IF clause was supplied or not. We could play games with boolean_factors(), but it becomes too tricky. The expressions are broken down back to boolean factors during prepare. We'll later consolidate them too.
