Pulling Guide

We use the [git flow model][http://nvie.com/archives/323] and therefore there (should) be two types of pull requests:

• [requests to merge in the branch someuser:cool-new-feature to ukhas:develop][Pulling Guide: New feature]
• [requests to merge in someuser:develop to ukhas:develop][Pulling Guide: Inline develop commits]

We'd like to be fairly strict about keeping to the model, so you should probably reject requests that don't conform to this pattern or requests where new features have been added straight into develop.
