/**
 * Interface required to implement the visitor design pattern.
 *
 * Two interfaces are required:
 * - *Visitable* should be implemented by classes to be visited, i.e. subclasses of Node.
 *      This interface consists of a single function `accept()`, called to visit the AST.
 * - *Visitor* should be implemented by AST transformers, and consists of one function for each subclass of Node,
 *      i.e. `visitXXXNode()`
 *
 *
 * LogicVisitor interface.
 *
 * Implemented by LogicEvaluator interpreter.
 * The interface specifies functions for visiting and handling each Node subclass.
