/**
 * ASTNode is an ancestor of all former ASTNodes.
 * It implements Visitable, which is an abstraction of something, which
 * can be visited, by visitor.
 * It is very important in our tree relation and creating tree crawlers,
 * such as ASTInspector, which is very helpful for debugging.
 * ASTNode stores its children in vector of pointers to other ASTNodes,
 * It allows us to use features of polymorphism.
