[pushed] wwwdocs: projects: Remove parser-related simple project(s)

[Gerald Pfeifer]

Christopher pointed out these did not appear applicable any longer.
From what I found I agree, so removed this from the beginner projects 
list.

Pushed.

-<p>All the logic here should be moved into a separate function in
-c-typeck.c, named something like parser_build_c_cast.  The point of
-doing this is, the less code in Yacc input files, the easier it is to
-rearrange the grammar and/or replace it entirely.  Also it makes it
-less likely that someone will muck with action code and then forget to
-rebuild the generated parser and check it in.</p>

-<p>We also want to minimize the number of helper functions embedded in

 <li>Break up enormous functions.
