+ ///
+ ///
+ /// This class can then be asked for the ith token in the input stream.
+ /// Useful for dumping out the input stream exactly after doing some

+ ///
+ ///
+ /// You can insert stuff, replace, and delete chunks. Note that the
+ /// operations are done lazily--only if you convert the buffer to a
+ /// string. This is very efficient because you are not moving data around
+ /// all the time. As the buffer of tokens is converted to strings, the
+ /// toString() method(s) check to see if there is an operation at the
+ /// current index. If so, the operation is done and then normal string
+ /// rendering continues on the buffer. This is like having multiple Turing
+ /// machine instruction streams (programs) operating on a single input tape. :)
+ ///
+ ///
+ /// Since the operations are done lazily at toString-time, operations do not
+ /// screw up the token index values. That is, an insert operation at token
+ /// index i does not change the index values for tokens i+1..n-1.
+ ///
+ ///
+ /// Because operations never actually alter the buffer, you may always get
+ /// the original token stream back without undoing anything. Since
+ /// the instructions are queued up, you can easily simulate transactions and
+ /// roll back any changes if there is an error just by removing instructions.
+ /// For example,
+ ///
+ /// For example:
+ ///
+ /// TokenStreamRewriteEngine rewriteEngine = new TokenStreamRewriteEngine(lexer);
+ /// JavaRecognizer parser = new JavaRecognizer(rewriteEngine);
+ /// ...
+ /// rewriteEngine.insertAfter("pass1", t, "foobar");}

+ /// You can also have multiple "instruction streams" and get multiple
