File structure

[brianlangseth-NOAA]

This is flexible and open for discussion. I wanted to set up a file structure early and jot down what each would house. This is based on the one I used for canary, which differs a little from what was done for copper last time.

Early proposal:
code - any R code
data - post-processed non-confidential data outputs from functions used within code files, or data ready for input into SS3
data-raw - raw data from which files in "data" are derived. This folder is ignored because it should not be pushed to github. Include a subfolder here "CONFIDENTIAL" for data that is confidential to the group so as to make it easy to separate when we archive
docs - where we would put any website material for viewing
documents - place for report writing materials (either from sa4ss or the new HQ template)
models - folder for model runs.

If we want to add R functions, which is what most of the code appears to be from the copper assessment, we can do so in the code folder
