> With sharing macros, colliding namespaces is very likely given that multiple 
> macros from different authors might import them in the same pig script. I 
> propose that we add namespaces to macros.
> We can either add a namespace command in macros, or name the space by the 
> filename.
> This ticket is needed to facilitate sharing of macros within and between 
> organizations and individuals in piggybank or on github or wherever.
