Param: usrDisplayName is the unique user ID for each user in the channel.
This will be compared to the hard coded user ID's, and when matched will 
create a payload object that will contain the weather api key and the users
location, contained in a private config file. These are kept separated to 
hide the user's location and weather api key.
