a generator for koa like express-genertaor
Long long ago,  I used express, and express-generator (https://github.com/expressjs/generator)

The lead of express team is said to  maintain the express-generator.

But when I found Koa, I think Koa is more simple to use .

Koa is greate.  If Koa has a generator like express-generator , koa will become more and more 

simple to use. 

The generator github.com/17koa/koa-generator has not been updated for a long time.
