Backend chat infrastructure using Message Hub

An identifier is created for each user of a chat service built using Message Hub.

The Message Hub Management API is used to create IDs for each user. When creating IDs, a password is also autogenerated.

Each application connects to the Message Hub service using the created credentials. The Melrose Labs SMPP Client can be used as a test application.

In the first application, a new message is addressed to the second application by entering the second application's identifier in the destination_addr field. The message "Hello World!" is typed and the "submit" button clicked.

The message should now apear in the seconds application.
