[Vala] GTK+ Tutorial

[Horace Abenga <horaceabenga gmail com>]

Hi all,

I'm planning on writing a comprehensive GTK+ programming using Vala tutorial
that will loosely follow the classic GTK+ tutorial
(http://developer.gnome.org/gtk-tutorial/2.90/).

I've done the first four chapters, which can be found (in docbook xml) on
https://github.com/abenga/valagtktutorial .

I'm requesting for comments, especially on coding conventions, best
practice coding
techniques, and any other suggestions of things I should include or
remove, before I
go too far.

Please check it out and let me know.

Horace.
