Test Plan (Steps to test):

1. Create a project with the Shape Portfolio template. Create an API key and save it for later.
2. Clone takeshape-samples if you don't already have it locally
3. Navigate to the shape-portfolio-gatsbyjs folder
4. Install the prerelease that was published from this branch npm install gatsby-source-takeshape@0.0.3-1
5. Edit gatsby-config.js
   1. Under plugins, change gatsby-source-graphql to gatsby-source-takeshape
   2. Remove all the existing plugin options
   3. Add apiKey and projectId options with the API key and project ID that you created earlier.
6. npm run start
7. Navigate to http://localhost:8000/ (or wherever it says you can view your site) and make sure it looks right
8. Test it again with a huge site
   1. In your gatsby-source-takeshape config, set refetchInterval to 0 to make this simpler
   2. In src/pages, make 1000 copies of index.html
   3. npm run start again
   4. Verify that although it takes much longer, it'll still build
   5. Test the site built correctly at a few of the random pages you made, eg http://localhost:8000/index%20copy%20300
9. Review the README and try all the options to make sure none of them break
