syntax tree builder and visitors generator for JavaCC

 JTB (Java Tree Builder) is a syntax tree builder and visitors generator to be
 used in front of JavaCC (Java Compiler Compiler). It takes a JavaCC grammar
 file as input (usually a ".jtb" file) and automatically generates the
  * a set of syntax tree classes based on the productions in the grammar,
    utilizing the Visitor design pattern;
  * four interfaces: IVoidVisitor, IVoidArguVisitor, IRetVisitor,
  * four depth-first visitors: DepthFirstVoidVisitor, DepthFirstVoidArguVisitor,
    DepthFirstRetVisitor, DepthFirstREtArguVisitor, whose default methods simply
    visit the children of the current node;
  * a JavaCC grammar ".jj" file (jtb.out.jj by default), with the proper
    annotations to build the syntax tree during parsing (which then must be
    compiled with JavaCC).
 New visitors, which subclass any generated one, can then override the default
 methods and perform various operations on and manipulate the generated syntax
