FRED API key
Users of fredr must authenticate with the FRED API by use of an
API key. This key should be stored as an environment variable,
FRED_API_KEY.
fredr_get_key() will retrieve the key, if set, or it will return NULL
if the key is unset.
fredr_set_key() will set the key for the current R session. For
persistence across sessions, set the environment variable.
See the Details section for more information.
fredr_has_key() returns TRUE if a key can be found. Otherwise it
returns FALSE.
fredr_set_key(key) fredr_get_key() fredr_has_key()

setting the key.
