Getting Started with Kiwi CatTools API

Is there a tutorial for getting started with the CatTools API? I'm finding the documentation in this area to be somewhat lacking. From the 9.1 Environments section:

In the VBA menu Tools/Reference select "Kiwi CatTools API" from the available references. 

Is this instruction speaking to how to setup the MS Visual Basic Editor? The 8.1 Script Editors section mentions that any script editor will do, however, basic text editors don't have the functionality to reference an external library. Where is the "Kiwi CatTools API" DLL (library) on the filesystem?

Given the 9.2.1.1 Sample Code used to establish a connection to the CatTools database via it's API. The the first variable in this script is cast as a CatToolsAPI.Database. How do you reference the "Kiwi CatTools API" library so that this script may cast this type of variable?

Dim DB As CatToolsAPI.Database
Set DB = New CatToolsAPI.Database
DB.EncryptionPassword = "MyPassword"
If DB.OpenConnection Then
MsgBox "Connected ok"
Else
MsgBox "DB connection failed: " & DB.ErrDescription
End If
DB.CloseConnection
Set DB = Nothing
