Creates an Azure Service Bus Topic.

Note: This example requires Chilkat v9.5.0.65 or greater.

'  Note: Requires Chilkat v9.5.0.65 or greater.

'  This requires the Chilkat API to have been previously unlocked.
'  See Global Unlock Sample for sample code.

'  Make the initial connection.
'  A single REST object, once connected, can be used for many Azure Service Bus REST API calls.
'  The auto-reconnect indicates that if the already-established HTTPS connection is closed,
'  then it will be automatically re-established as needed.

'  ----------------------------------------------------------------------------------------------
'  The code above this comment could be placed inside a function/subroutine within the application
'  because the connection does not need to be made for every request.  Once the connection is made
'  the app may send many requests..
