tutoral/example of gtk sourceview

["Frank Atta" <atta hollander gmail com>]

I'm using GTKSourceView in a project of mine, and noticed there isn't to much of a tutorial/example online. 
I wrote an example code for GTKSourceView 2.0

It shows the line numbers and highlights C source.  I guess any programmer can figure out how it works :p

Thanks for this widget!
