I believe the plan is to hold off on merging this before we decide what's up with the us-v-Sollya comparisons. |

This branch introduces an idea of sharing exponents among sampling runs.
This feature speeds up 'problematic' benchmarks where more that 1 iteration is usually spent for sampling.
In this branch,
vstart-precsis dynamic and changes with the number of runs, wherevstart-precsis the vector of precisions that are to be tried on the first iteration.The main formula for change is:
vstart-precs += ceiling(alpha * (vprecs - vstart-precs))
