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

* ----------------------------------------------------------------------
* This initial setup, which involves setting the OAuth1 properties and connecting
* to api.twitter.com, is only required once at the beginning.  Once connected, the same
* object instance may be re-used, and if necessary, it will automatically reconnect
* as needed.

* Assume we've previously obtained an access token and saved it to a JSON file..
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')
loJson = CreateObject('Chilkat.JsonObject')
lnSuccess = loJson.LoadFile("qa_data/tokens/twitter.json")

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Rest')
loRest = CreateObject('Chilkat.Rest')
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.OAuth1')
