Create Example To Modify A File Identification

[romeara]

Create an example of using the Protex SDK to remove an identification from a file, and add a new one (effectively modifying the identification)

[hch-2k8]

A simple example how to identify a given code match as original to a project would be very useful as well. All my attempts have failed so far.
Believe or not, Protex is not dead yet.
Please...
