INSTRUCTIONS
This sample performs authorization on various OAuth 1.0 services and
then requests basic user information.
This sample is for Windows Desktop, OS X and Linux.
Execute with administrator privileges.
Set the app key & secret strings below (i.e. s_linkedin_key, s_linkedin_secret, etc.)
To get key & secret, register an app in the corresponding service.
Set following entry in the hosts file:
127.0.0.1 testhost.local
