Add the full grant proposal for CZI to the repo

[melissawm]

We have decided to add a link to the figshare document in our team page instead of adding the PDF binary to this repo. This keeps the repo lighter and the figshare document should be pretty permanent.

Thanks for the suggestion, and please reopen if you'd like to see a different suggestion 😄
