      The SamplingEstimator calculates the size of a sample based on the confidence level and margin of error required.

      The required confidence level and margin of error can be configured via query knobs.

      The sample shouldn't be too big, so we provide 3 levels of confidence interval 99%, 95%, 90%. The margin of error should also be constrained in order to limit the sample size.
