Protected function "AcceptInput", proved to the user DLL for registering input types acceptable by the DLL for computation. This function should be invoked in Init()()(), and the registered acceptable input types will be passed to Visual Signal's ExternalDll module via getDllInfo()()(). Visual Signal will use this information to determine whether an input connection is valid or not.
