Provide options to change what happens after successfull sign in

[himanshu0128]

I am using this library for Oauth authentication. The next() function does the job of what happens after successfull sign in but rest of the things are handled by the library itself. Every application has its own authentication scheme and the option to set cookies should be given to the application and not the library. Currently the library sets authheaders as cookie after token validation call. I want to change it as per my application but i am not able to do so.
