# Example: print 10 latest posts from the user's home feed.
# 
# Instead of using a config file to read & store authentication info, this example uses a custom
# client class which reads the password from the console and creates a throwaway access token.
#
# This approach makes sense for one-off scripts (e.g. in manually run Rake tasks), but it shouldn't
# be used for things that need to be done repeatedly and often. The authentication-related endpoints
# (createSession) have much lower rate limits than others and they don't reset as quickly,
# and you are likely to hit them if you call the endpoint over and over during testing.
