/**
 * Factory for creating AST nodes. This interface contains factory methods
 * for nodes that are available for both C and C++.
 * 
 * Extending interfaces should use covariant return types where appropriate to
 * allow the construction of language-specific versions of certain nodes. 
 * 
 * Most methods accept child nodes as parameters when constructing a new node.
 * For convenience it is always allowed to pass null for any of these parameters.
 * In this case the newly constructed node may be initialized using its 
 * set() and add() methods instead.
 * 
 * Nodes created by this factory are not frozen, i.e. for any node created by this
 * factory the following holds <code> node.isFrozen() == false </code>.
 * 
 * None of the factory methods should return null.
 * 
 * @since 5.1
 * @noextend This interface is not intended to be extended by clients.
 * @noimplement This interface is not intended to be implemented by clients.
