Debugging test 5:
 - For the effort and months model, you can compare outputs from your
   system to http://sunset.usc.edu/research/COCOMOII/expert_cocomo/expert_cocomo2000.html.
   The source code for that system is at /nova/etc/cocomo.c. Try and explain
   any differences between your code and expert cocomo

Expert COCOMO Output:
Effort: 13623 person-months
Schedule: 106.6 months

NOVA Outputs:
Effort: 6360.1 person-months
Schedule: 90.2 months

The outputs for schedule are very close and within a reasonable error given
that we are choosing random values for the slopes of the effort multipliers 
and scale factors.  The outputs for effort are way off.  We are unsure of the
cause of this problem as we have found no bugs in effort-model.lisp.
