object Histogram

A Basic log-scale histogram, mainly designed to measure latency

Each bucket handles an increasingly large range of values from 0 to MAX_INT.

    generate some bucket ranges for a histogram.

    generate some bucket ranges for a histogram. inifnity is the lower bound of the last bucket. You can set this to a value lower than MAX_INT when you're confident most values will be below it. For example, if you're measuring processing latency, and you're sure a request will never take more than 1000ms, you can set infinity to this, which will greatly improve accuracy for values below, but all values above will be lumped into a single bucket
