twisted.cred documentation is unclear about CredentialChecker implementations

New submission from rlotun <[email protected]>:

I read this paragraph from the twisted cred documentation tutorial:

{{{
This is an object implementing ICredentialsChecker which resolves some Credentials to an avatar ID. Some examples of CredentialChecker implementations would be: InMemoryUsernamePassword, ApacheStyleHTAccessFile, UNIXPasswordDatabase, SSHPublicKeyDatabase. A credential checker stipulates some requirements of the credentials it can check by specifying a credentialInterfaces attribute, which is a list of interfaces. Credentials passed to its requestAvatarId method must implement one of those interfaces.
}}}

And it led me to believe that `ApacheStyleHTAccessFile` actually existed. Of course, I think the intention was that it ''could'' be a possible implementation. Anyway, this needs to be reworded a bit more clearly.
