Use a token model for authentication.
A custom token model may be used here, but must have the following minimum
properties:
* key -- The string identifying the token
* user -- The user to which the token belongs
* revoked -- The status of the token
The BaseToken class is available as an abstract model to be derived from.
The token key should be passed in as a string to the "Authorization" HTTP
header. For example:
Authorization: Token 0123456789abcdef0123456789abcdef
