## routes
if a route requires a parameter, it will be notated like <this>.
for example; if a route is notated as "/api/v1/route?<parameter>", you can
access that route via the url
"http://this.domain/api/v1/route?parameter=something"

- /api/v1
  - /: index page (you are here)
  - /statistics?<short>: get information about a short url; long, disabled, uses
  - /create: a post route which takes a form; long and short, creates a new
    short url
