1. Run tests: karma start
2. Run build: gulp app
3. Run server: nodemon server.js (you can use 'node server.js', but autoreload won't work)
Troubleshooting
If karma throws an error 'phantomjs not installed' and you're using Windows,
make sure to copy it from '/node_modules/phantomjs/lib/phantom/bin/phantom.exe' into your
'C:\Users\your_user\AppData\Roaming\npm' folder.
