+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
+```
