##### A decorator that logs the method or get property when it is called

#### Install
``console
$ npm install @dekor/logger
`

#### Logger vs LoggerLegacy
For those who use @babel/plugin-proposal-decorators:

- If the decorated class contains private methods (marked by '#'),
use LoggerLegacy, set the plugin: [ '@babel/plugin-proposal-decorators', { legacy: true } ].
because the @babel/plugin-proposal-decorators plugin under 7.10.4 version hasn't supported private fields yet.
- Otherwise, use Logger, set the plugin: [ '@babel/plugin-proposal-decorators', { legacy: false } ].

#### Usage - stage 2 mode
`js
import { Logger } from '@dekor/logger'
// if the class contains private field
// import { LoggerLegacy } from '@dekor/logger'

const logger = Logger('decorator:logger')


class Point {
constructor(x, y) { this.x = x; this.y = y }

@logger
get distance() { return Math.sqrt(this.x 2 + this.y 2) }
}

const p = new Point(3, 4)
p.distance |> console.log

// console outputs:
// > [decorator:logOnCall] 18:29:49.008 calling property Point.distance
// > 10
