FAQ page created

Hi. 
I have decided to get this rolling although I think It would be an odd faq section with only one very specific question. I will go through some of the issues and see what I find but it will be mostly questions that I have. 

I also imagine the markdown choice could be improved and that the example might be rather large for every question. 

That said I think code examples are great and even more so for testing. I find that if I ever end up not testing a piece of code it was because i tripped up write at the beggining with a new great gem but being unable to work out what to hook on to test
