Clojurians Log v2

I've updated http://pedestal.io/pedestal/0.7/guides/embedded-template.html to show how to use the correct version number when creating a new project.

I did some very rough performance checks, old (interceptor) vs. new (routes):

;; Rough test using Apache Bench, on single OS X M1 Mac
;; ab -n 1000 -c 4
;;
;; Mean time/request (ms)
;;
;; Test                          Interceptor                       Routes
;; ----------------------------------------------------------------------
;; small file                    1.8                               1.07
;; large file                    1.09                               .6
;; small resource                 .8                                .69
;; large resource                1.05                               .38
;; file: index of dir             .89                               .47
;;
;; Route column was collected with interceptors NOT present
;; (times were worse with both interceptors and routes enabled).
;; Ran each ab command several times in a row, until the numbers
;; looked reasonably stable.

After I get resources worked out, I want to figure out how to get it so that you expose web sockets as routes.

And I’m also interested in opening up the telemetry to support doubles, not just longs.
