App to share: reading and writing categories.

This was just written to test/demo how to read the categories of a file and how to write one category
to a file.

To use just unzip the file into the user directory:  C:\ProgramData\photools.com\imatch6\webroot\user

Looks like the zip file is missing

Sorry - fixed.
