koa-dispatcher v0.0.6

koa-dispatcher

The name "dispatcher" is actually misleading. It could be better named "koa-composer", as it composes multiple handlers into one, using flexible rules to decide the handler(s) to execute; but I named it "dispatcher", to avoid unnecessary confusions with the existing (and used in koa core) koa-compose.

Documentation is to be updated to reflect the recent major refactor.
