30    * We begin the Caliper tutorial with the simplest benchmark you can write.
35    *  - We write a class that extends com.google.caliper.Benchmark.
36    *  - It contains a public instance method whose name begins with 'time' and
38    *  - The body of the method simply executes the code we wish to measure,

64    *  - We simply add another method, following the same rules as the first.

102    * Caliper reported that the benchmark above ran in 4 nanoseconds.
108    * It is very important to sanity-check benchmark results with common sense!
116    *  - We simply change the 'time' method from 'void' to any return type we
