[pygccxml-development] Patch to add a little syntactic sugar

[Allen B. <al...@vr...>]

I have included a patch that I find useful for simplifying decl lookup 
in pyplusplus.

It allows code like the following to be written using the __getitem__ 
interface.

ns = mb.global_ns.namespace( 'my_ns',)
ns["MyClass"].exclude()
class_a = ns["ClassA"]
class_a["doSomething"].include()

It also allows an attribute interface (similar to Pyste). 

ns.MyClass.exclude()
class_a = ns.ClassA
class_a.doSomething.include()

These both can be used to dramatically reduce the amount of clutter 
(redundant code calls) using in a script to generate bindings. Although 
the second one could be seen as a little dangerous because of potential 
name conflicts, I think the interface of Pyste has proven that people 
like an interface like this because it allows something that feels like 
a very tight domain specific langauge for creating bindings.

I know that neither of these methods is anything more then syntactic 
sugar, but IMHO it is pretty sweet sugar. :)
