erapse : show elapsed time of go function

How to use

Import time and github.com/UedaTakeyuki/erapse and just call defer erapse.ShowErapsedTIme(time.Now()) at the beginning of the function you want to measure elapsed time, that it! Fx:

import (
	"time"
	"github.com/UedaTakeyuki/erapse"
)

func DoSomething(){
	defer erapse.ShowErapsedTIme(time.Now())

The result is as follows:

eraps main.DoSomething: 1896985 μs

Measurement error

On Intel PC, The ShowErapsedTIme itself consumes several microseconds.
On RPi, this consumes several tens of microseconds.

See the go test -v -run Test_04 under the test folder for more details.

By the way, why is "erapse" spelt R? Why not L of "elapse"?

Due to my mother language being Japanese which doesn't have a difference in pronunciation between R and L, I carelessly misspelt it. ^^; By the time I noticed the mistake, I had already used it a lot, so it was hard to correct the spelling now, so I thought it was okay and left it as is. I'm sure there are many other typos and grammatical errors in the document I wrote, so please feel free to point them out. Thx!

for other language
