[antlr-interest] Parser and TreeParser

[Benhur]

In the document "Runtime.html", under the section "What ANTLR 
generates", the below code is written. Do I need to write the 
MyParser extending Parser class also, if I want MyParser to extend 
TreeParser class or just extending TreeParser class is enough. 
Please let me know.

Thanks in advance
Benhur
