How to create a new type of board

[hadley]

Start by implementing each of the following functions in order to get the basic functions of a board working:

• Constructor
• pin_list() and/or pin_search() depending on how many pins you expect
• pin_exists()
• pin_meta()
• pin_fetch()
• pin_versions()
• pin_store()

Next get all of the cross-board tests working:

• test_api_basic()
• test_api_versioning()
• test_api_meta()

Check test coverage, and make sure you have extra tests for any specific behaviour that this board should possess.

What if we documented this as a README inside of R/, instead of a user-facing vignette? parsnip has one of these, and it seems like a good, low-lift option for this kind of developer-facing info.

I don't love it, just because I personally would have no idea to look there.
