/**************************************************************************
* IQueryAssociations
*
* DESCRIPTION
* This object provides a layer of abstraction over the system registry in
* order to simplify the process of parsing associations between files.
* Associations in this context means the registry entries that link (for
* example) the extension of a file with its description, list of
* applications to open the file with, and actions that can be performed on it
* (the shell displays such information in the context menu of explorer
* when you right-click on a file).
*
* HELPERS
* You can use this object transparently by calling the helper functions
* AssocQueryKeyA(), AssocQueryStringA() and AssocQueryStringByKeyA(). These
* create an IQueryAssociations object, perform the requested actions
* and then dispose of the object. Alternatively, you can create an instance
* of the object using AssocCreate() and call the following methods on it:
