Install development dependencies

Part of the deployment of Rodan Client is the installation of build dependencies. These are declared in the devDependencies section of package.json. When npm install is run from the root repository directory (i.e. rodan-client), npm downloads and installs each of the development dependencies in rodan-client/node_modules.

user@computer:~$ cd rodan-client
user@computer:~/rodan-client$ npm install
