Initial Commit - Working MEAN stack project

@AusMUG/team1 @ayasin @cdnadmin Here is a PR with a working MEAN stack project structure. I have tried to keep things pretty simple building the structure manually instead of going for a Yeoman generated project. I've put in some details in the Readme file about some of the choices I made. I have also put in the instructions to setup and run the project locally.

Please let me know if you want me to make any changes to the structure or any of the associated processes.
