[ndnSIM] Number of requests / interests expressed by ConsumerZipfMandelbrot

Greetings again,
I think maybe I need to rephrase my issue/question(s):
- It seems that no matter which of the built-in Consumer classes that I
use, the first content object requested gets the most frequent requests,
then the second, then the third, etc.
- Are there any Consumer classes and/or setting combinations that will
lend to a more random set of requests from various consumers?
- E.g., Consumer1 might request content object %FE%04 more frequently
than 03 or 01
- E.g., Consumer2 might request content object %FE%05 most
frequently, then 03, then 01, then 02, etc.
I just want something a little more realistic.
Do I need to create a custom Consumer subclass for this behavior or are
there settings that will allow for this. I found the
SetAttribute("Random", ....) doesn't really make anything truly random, so
I suspect maybe there's another setting I'm missing.
Thanks,
John
