Commented on "Testing" focus of Angular tutorial. Completed Env setup section. Added profile. Other Misc edits ....

Done:
-----

* Added point to **AngularJS section** of instructions telling students to ignore the testing focus of the official AngularJS tutorial. 
* Filled out the **Environment setup section** of instructions. Was unsure after last meeting (18/10/2013) if the `rhc` command line utility will be pre-installed on students machines. If this is the case then the instructions should be edited to mention the command for separately setting a namespace, rather than as a part of `rhc setup`. I specified that students should use their student number as a domain name; this is just a placeholder, but I thought it sensible to come up with some consistent scheme. 
* Edited **Run Example section** to account for the `APPLICATION_TYPE` specified in the README.md being incorrect. May submit pull request to central jdf repository on that front if others confirm the issue. 
* Added demonstrator profile. 

Comments:
-----

* I agree with Ryan's comment about providing a "_ready made_" github repo containing the `kitchensink-angularjs` application as opposed to simply providing a link to the JDF website for a number of reasons:
    * The JDF requires they sign up for an additional service (we already ask them to sign up for 2).
    * The `kitchensink-anguarjs` pom doesn't declare the jdf pom as a parent. The jdf pom is not required.
    * When downloading or cloning the jdf - the multitude of other projects downloaded is only confusing. There is a risk that some students might choose the wrong one. Even if they do not they will only end up deleting the others. 
    * If example code snippets is the motivation - then supplying [this link](https://github.com/jboss-developer/jboss-wfk-quickstarts) would achieve that and also further familiarise them with the Github tools and interface.
* I have completed the tutorial and got the environment setup (only stumbling block is apparently `rhc` doesn't like `jruby`). The coursework will follow later in the week when I have a spare moment.
