Feature/add people tool

1)Added logic for editing a section. Provided the helper method to invoke the API - needs to plugin the UI logic to invoke this. 
2)Unit tests to follow. This is the next task I have on my list. 
There is a risk of an injection attack, but in this case it seems fairly minor. We'll be coming up with a general strategy for input validation in the future, so until then we can just focus on the most concerning ones.

The issue I was raising was whether there could be a case where desired_section_name was, say, an integer, and that we then called strip() on it. If you're sure that the variable can only ever be a String that's not a problem.

My kingdom for some static types...
