54891af88d More lenient double comparison for RunningStatistics.FullSimpleTest 
The test was failing (in a flaky fashion, interestingly), comparing:
* 50.5 whose mantissa is:
1001010000000000000000000000000000000000000000000000
* with 50.500000000000036 whose mantissa is:
1001010000000000000000000000000000000000000000000101

since EXPECT_DOUBLE_EQ() only allows 4 ULPs difference.
We don't need this kind of precision.

Most of these changes are clang-format grouping and reordering includes
differently.

3dfb68082e Use robust variance computation in RollingAccumulator. 
Previous one was failing NumericStabilityForVariance test.

890f62b8fe Provide robust and efficient variance computation for online statistics. 
This CL implements Welford's algorithm for a
numerically stable computation of the variance.
This implementation is plugged in SamplesStatsCounter class (adapter pattern).

A 'NumericalStability' unit test has been added,
whose previous implementation of SamplesStatsCounter failed to pass.

Follow-up CLs will factorize more occurences of duplicated and misbehaved
computations.
