Improve tools for modifying and updating the wisdom pod

This is an idea that Ying suggested. I'm starting a formal issue to track its progress since I'm currently investigating it.

The idea is that we should be able to streamline the process of modifying the SwiftWisdom pod. When a developer is working on a project that uses wisdom, if they run into a situation where they feel that wisdom should be modified, they need to undertake a few steps:

1. Switch their pods setup to allow them to work with a local development version of wisdom such that they can modify the pod, work against those modifications, and have those changes tracked in git.
2. Create a pull request for their changes to be included in master.
3. After merge, publish the update for others to consume.

The idea is to provide a set of tools, like say helper scripts, to help automate this process and make it easier for devs to contribute to wisdom without breaking stride on their client projects.

@andrewdolce can we make more issues and tasks for this item when you get a chance?
