Implemented LinkedInDeveloperAuthentication class that stores the 4 credentials necessary for an OAuth 1.0a flow and modified LinkedInApplication to use requests_oauthlib to do all of the heavy lifting in enabling the OAuth 1.0a flow that requires no redirects or user intervention in the event that it is passed a LinkedInDeveloperAuthentication instance. Very useful for situations in which users just want to access their own data or when developers are testing. Have not updated the README docs yet
Updated README.md with minimal documentation to use the new LinkedInDeveloperAuthentication class
