I just started to take notes of the implementation details of Pd on
pdpedia. I think this could be a good place to develop documentation
about how Pd's implementation works. Here's my first two attempts.

of comments formatted to be parsed by doxygen to have nice docs of
the internals. These are some I'd like to know more about:

t_gobj t_object t_text

And anything else people feel like writing about...
