Example usage of this module:
```v
import benchmark
mut bmark := benchmark.new_benchmark()
// by default the benchmark will be verbose, i.e. it will include timing information
// if you want it to be silent, set bmark.verbose = false
for {
bmark.step() // call this when you want to advance the benchmark.
// The timing info in bmark.step_message will be measured starting from the last call to bmark.step
// ....
// bmark.fail() // call this if the step failed
// bmark.step_message(('failed')
bmark.ok() // call this when the step succeeded
println(bmark.step_message('ok'))
}
bmark.stop()
// call when you want to finalize the benchmark
println(bmark.total_message('remarks about the benchmark'))
```
benchmark.start() and b.measure() are convenience methods,
intended to be used in combination. Their goal is to make
benchmarking of small snippets of code as *short*, easy to
write, and then to read and analyze the results, as possible.
Example:
```v
import time
import benchmark
mut b := benchmark.start()
// your code section 1 ...
time.sleep(1500 * time.millisecond)
b.measure('code_1')
// your code section 2 ...
time.sleep(500 * time.millisecond)
b.measure('code_2')
```
... which will produce on stdout something like this:
```text
SPENT 1500.063 ms in code_1
SPENT 500.061 ms in code_2
```
