>   
>   context.defineNamespace("Math").add( java.lang.Math.class  ) ;
>    used as $Math.sin(0)
> 2) Add / Replace / remove methods in namespace :
>   context.getNamespace("Math").add(MyRandom.class.getMethod("randomString",new 
> Class[]{int.class}))
>   used as $Math.randomString(12)
> 3) "union" on namespaces
>  context.defineNamespace("Utils")
>           .add(context.getNamespace("Math"))
>           .add(context.defineNamespace("Collections",Collections.class ) );
>  used as:
>   $Utils.sin(0)
>   $Utils.sort($list)
> 4) Global namespace
>   context.getGlobalNamespace().add( Math.class ); 
>   used as $sin(0)
> 5) inline namespaces:
>  #use java.lang.Math as Math
>    $Math.sin(0)
