`Delegation`__
==============
Purpose
-------
Demonstrate the Delegator pattern, where an object, instead of performing one
of its stated tasks, delegates that task to an associated helper object. In
this case TeamLead professes to writeCode and Usage uses this, while TeamLead
delegates writeCode to JuniorDeveloper's writeBadCode function. This inverts
the responsibility so that Usage is unknowingly executing writeBadCode.
Examples
--------
Please review JuniorDeveloper.php, TeamLead.php, and then Usage.php to see it all tied together.

You should look at and run the tests to see what happens in the example.
To do this, you should install dependencies with `Composer` first:
### [optional] Using Docker
You can optionally run tests using [Docker for Mac](https://www.docker.com/docker-mac) or [Windows](https://www.docker.com/docker-windows) or native one for [Linux](https://www.docker.com/docker-debian).
Just run:
```
docker-compose up
```
### Install dependencies
```bash
$ composer install
```
Read more about how to install and use `Composer` on your local machine [here](https://getcomposer.org/doc/00-intro.md#installation-linux-unix-osx).
If you are using Docker, you just have to run:
```bash
docker-compose run composer install
```
### Running test suite
To run the tests use `phpunit`:
```bash
$ ./vendor/bin/phpunit
```
