Why is the output non-deterministic?

I've found that running dupl on the same codebase multiple times produces different results. I'm not sure why this would be the case, any ideas?

Heres some examples to demonstrate what I mean:

>for i in $(seq 1 100);do dupl ~/go/src/github.com/spf13/cobra/ |grep Found;done  |sort |uniq -c
      6 Found total 82 clone groups.
     27 Found total 83 clone groups.
     52 Found total 84 clone groups.
     13 Found total 85 clone groups.
      2 Found total 86 clone groups.
> for i in $(seq 1 100);do dupl ~/go/src/golang.org/x/net/webdav |grep Found;done  |sort |uniq -c
      2 Found total 228 clone groups.
     30 Found total 229 clone groups.
     30 Found total 230 clone groups.
     23 Found total 231 clone groups.
     12 Found total 232 clone groups.
      3 Found total 233 clone groups.

I don't see a way to check the version of dupl I have installed, but I just updated to the latest commit as of the time of me posting this ticket (415e882)

Having it written a while ago, my guess is because of using maps. Anyway I think it definitely should be deterministic. I'm gonna take a look at it when I have time.
