	// Knuth, "The Art of Computer Programming", Vol. 2, page 323, 3rd edition

	// Bucket counts are given in order under the numbering scheme described

	//
	// The size of `bucket_counts` must be no greater than N as defined in
	// `bucket_options`.

}

Distribution contains summary statistics for a population of values and, optionally, a histogram representing the distribution of those values across a specified set of histogram buckets.

The summary statistics are the count, mean, sum of the squared deviation from the mean, the minimum, and the maximum of the set of population of values.

The histogram is based on a sequence of buckets and gives a count of values that fall into each bucket. The boundaries of the buckets are given either explicitly or by specifying parameters for a method of computing them (buckets of fixed width or buckets of exponentially increasing width).

Although it is not forbidden, it is generally a bad idea to include non-finite values (infinities or NaNs) in the population of values, as this will render the `mean` and `sum_of_squared_deviation` fields meaningless.

A Distribution may optionally contain a histogram of the values in the population. The histogram is given in `bucket_counts` as counts of values that fall into one of a sequence of non-overlapping buckets. The sequence of buckets is described by `bucket_options`.

A bucket specifies an inclusive lower bound and exclusive upper bound for the values that are counted for that bucket. The upper bound of a bucket is strictly greater than the lower bound.

The sequence of N buckets for a Distribution consists of an underflow bucket (number 0), zero or more finite buckets (number 1 through N - 2) and an overflow bucket (number N - 1). The buckets are contiguous: the lower bound of bucket i (i > 0) is the same as the upper bound of bucket i - 1. The buckets span the whole range of finite values: lower bound of the underflow bucket is -infinity and the upper bound of the overflow bucket is +infinity. The finite buckets are so-called because both bounds are finite.

`BucketOptions` describes bucket boundaries in one of three ways. Two describe the boundaries by giving parameters for a formula to generate boundaries and one gives the bucket boundaries explicitly.

If `bucket_boundaries` is not given, then no `bucket_counts` may be given.

type Distribution_BucketOptions_Explicit 

type Distribution_BucketOptions_Explicit struct {
	// The values must be monotonically increasing.
	Bounds []float64 `protobuf:"fixed64,1,rep,packed,name=bounds" json:"bounds,omitempty"`
}

A set of buckets with arbitrary widths.

Defines `size(bounds) + 1` (= N) buckets with these boundaries for bucket i: 

Upper bound (0 <= i < N-1):     bounds[i]
Lower bound (1 <= i < N);       bounds[i - 1]

There must be at least one element in `bounds`. If `bounds` has only one element, there are no finite buckets, and that single element is the common boundary of the overflow and underflow buckets.

}

Specify a sequence of buckets that have a width that is proportional to the value of the lower bound. Each bucket represents a constant relative uncertainty on a specific value in the bucket.

Defines `num_finite_buckets + 2` (= N) buckets with these boundaries for bucket i: 

Upper bound (0 <= i < N-1):     scale * (growth_factor ^ i).
Lower bound (1 <= i < N):       scale * (growth_factor ^ (i - 1)).

Defines `num_finite_buckets + 2` (= N) buckets with these boundaries for bucket `i`: 

Upper bound (0 <= i < N-1):     offset + (width * i).
Lower bound (1 <= i < N):       offset + (width * (i - 1)).
