boost::python::arg maybe a bit long?

[Bruno Chareyre]

When a function as many default parameters in YADE_CLASS macros it increases the code seriously.
possible fix:
#define boost::python::arg arg
+ search/replace

Hi Bruno,

I am not the fan of "#defines", and I would propose to
use something like:

namespace py = boost::python;

what is used already in some parts of the code [1]. I think
it will be more safely and reduces this expression.

That would do the trick too. Ok.
