[IMP-dev] More small patches

[Daniel Russel <>]

practice). Second I loosed the tolerances on one of the tests since it  
was often outside the tolerance if anything changed with the state of  
the random number generator.

I added a call to seed the random number generator with the current  
time and a comment about how to set the seed if you prefer something  
else.
