test git credentials
sucessfully scrape curl response for user email
* there has GOT to be a way to access the resp like a hash table, but
i suppose this'll do for now.
create authors file && cat authors to it
* set git user name & email
* pseudocode eventual functionality
script can cycle through author names
* get_author reads the top line of the file & stores it
* cycle_author deletes the top line and appends it (from memory) to the
bottom
* optimize pull_email slightly by plling out the call to sed
refactor author CRUD functions
* save filepath to variable, use that throughout
* guard against duplicate usernames being added, piped to dev/null
script now takes arguments
* refactor authors file creation
* add () to each function. lol
* script can now return current user
move git functions to post-commit hook
* add list_authors function
squished bug where sed was creating files
* sed needs to be passed a blank string after -i flag if you're doing
deletion
set author info in post-commit.sh using sed
* need to check for existence of information already being there
to guard agaist duplicate info being appended
* use double quotes to interpolate for sed
