/**
* Visitor interface for the abstract syntax tree. This class is tightly bound to the
* implementation of @ref ASTNode::accept and its overrides. After a call to
* @ref ASTNode::accept, the function visit for the appropriate parameter is called and then
* (if it returns true) this continues recursively for all child nodes in document order
* (there is an exception for contracts). After all child nodes have been visited, endVisit is
* called for the node.
