Please modify github documentation and a NodeJS library. This says otherwise:
http://auth0.github.io/node-auth0/module-auth.DatabaseAuthenticator.html#requestChangePasswordEmail
Need to remove this in this case.
Also remove this method from documentation:
requestChangePasswordEmail()
http://auth0.github.io/node-auth0/module-auth.DatabaseAuthenticator.html#requestChangePasswordEmail
please update documentations.
