- code goes into /src

- prose in /doc

- /experimental is a playground

We now run jobs w/o limits. This is probably bad in a hosted setup but
we can worry about that later should it ever become a problem. As it
stands the implementation is easier with a simple goroutine rather than
a complicated pool of threads.

- Not perfect yet. I think Job should be a struct so
  Collector can modify its members easily.
