+ * General purpose tool for examining random number distributions.
+ *
+ * Input -
+ * (a) a random number generator, and
+ * (b) the buckets:
+ * (1) number of buckets,
+ * (2) width of each bucket, in log scale,
+ * (3) expected mean and stddev of the count of random numbers in each
+ * bucket, and
+ * (c) number of iterations to invoke the generator.
+ *
+ * The program generates the specified amount of random numbers, and assess how
+ * well they conform to the expectations: for each bucket, output -
+ * (a) the (given) expected mean and stddev,
+ * (b) the actual count and any interesting level of deviation:
+ * (1) ~68% buckets should show no interesting deviation, meaning a
+ * deviation less than stddev from the expectation;
+ * (2) ~27% buckets should show '+' / '-', meaning a deviation in the range
+ * of [stddev, 2 * stddev) from the expectation;
+ * (3) ~4% buckets should show '++' / '--', meaning a deviation in the
+ * range of [2 * stddev, 3 * stddev) from the expectation; and
+ * (4) less than 0.3% buckets should show more than two '+'s / '-'s.
+ *
+ * Technical remarks:
+ * (a) The generator is expected to output uint64_t numbers, so you might need
+ * to define a wrapper.
+ * (b) The buckets must be of equal width and the lowest bucket starts at
+ * [0, 2^lg_bucket_width - 1).
+ * (c) Any generated number >= n_bucket * 2^lg_bucket_width will be counted
+ * towards the last bucket; the expected mean and stddev provided should
+ * also reflect that.
+ * (d) The number of iterations is advised to be determined so that the bucket
+ * with the minimal expected proportion gets a sufficient count.
