Initial branding stuff

As we are getting closer to production, may be it's good to have this discussion now only.
Some of the points:

1. How we should write "transtats" like

   • transtats
   • Transtats
   • TranStats
   • TRANSTATS

2. May be design of symbol or mark for transtats and if that design is combined with "transtats" text, could be called as logo!

   • The design should reflect concept of language statistics: may be some alphabet/s and stats (graphs, charts).

@juhp @pnemade please add your views, points

I think the name "Transtats" is okay, but open to other ideas or discussion. :)

Current logo is just a placeholder. Feel free to submit better designs.
