def avg(ary)
  sum = eval ary.join('+')
  sum.to_f / ary.size
end

#branch_realtime_measure ⇒ Object

When called with a block, runs the block code in each branch given. If we were only initialized with one branch, adds the current branch to the list of branches to test against. Restores state by checking out original branch after execution, and returns hash of time results on each branch.
