Make bisect results a little more scannable.
Make bisect results a little more scannable.

Do some refactoring along the way to separate presentation and logic.

Example new output:

 __o_\___          Aw Snap! We hit a speed bump!
=-O----O-'__.~.___________________________________

Bisect reproduced a -100.00% (+-0.00%) change in the floats_50_100/floats_50_100 metric.
Confidence in Bisection Results: 0%

WARNINGS:
  !!! Confidence is less than 100%. There could be other candidates for this regression. Try bisecting again with increased repeat_count or on a sub-metric that shows the regression more clearly.
