   This adds the randomization to RandomCodec and addresses some test issues.
   
   * In a few places I had to disable the randomization; basically wherever we 
are carefully testing scores. In these cases we won't have the same testing for 
quantized scores, but I think those would require more targeted testing since 
it's unclear what kinds of guarantees we can make about score values under 
quantization.
   * In a few other palces I added some slop to the score comparisons; 
basically if we had a score comparison in a test that was primarily focused on 
other things (like testing Explain)
   * I fixed a divide-by-zero edge case in the ScalarQuantizer (when there is 
only a single vector in a segment)
   * I standardized bounds checking so we have consistent exception messages 
for dimension mismatches
