Overview
************************************************************************
This application is an example of inheritance usage 
for FTP/FTP_DATA flows.
The application implements a small table that will store flows 
along with related metadata (FTP filename). 
When an FTP flow is classified, the application will store 
the FTP flow pointer and the parent key in a table entry. 
When a filename transfer is engaged, the application will 
add the filename information in the appropriate flow entry.
When an FTP_DATA flow is classified, the application will 
search for the flow inheritance key in the table and
if lookup is successful it will display 
the parent FTP flow and filename for this FTP_DATA flow.
