Example project to test hapistrano's working_dir feature

We're going to test the hapistrano's working_dir feature by deploying this project to a local server (Virtual machine). To do this we need to:

Install VirtualBox
Install Vagrant
You must have a ssh key with the name id_rsa. If you're not sure this article can be helfpul.
Go to the /hapistano/example directory.
Execute in your terminal the next line.
```
#This could take a couple of minutes
$ vagrant up
$ hap deploy
```
If everything went good, this should trigger the deployment procces to the virtual machine.
To check that the project was built you can ssh the vagrant vm, and do the folowing:
```
vagrant ssh
cd /tmp/hap-examle/current/example
stack build
```
Nothing should happen since your project is already compiled.
