    File:       ACInsertManager.h   

    Abstract:   Implements the Audio Context Insert Manager which functions as

                a factory for creating and configuring Audio Context insert 

                processor objects. At any given time, the ACInsertManager has 

                one processor instance associated with it as the 'current processor'.

                This is the instance that responds to the AC Insert window controller

                UI. The Audio Context Manager may also have an 'extraction processor'

                instance which is used for insert processing during extraction

                and extraction preview.
