Set Entry Filepath (in output Zip) when Zipping

Demonstrates how to set the path for the file entry within the .zip to something different than the path in the filesystem. C

    //  When an absolute filepath is passed to AddFile, the path within the .zip
    //  will be one of two values:  (1) just the filename part if saveExtraPath is FALSE,
    //  or (2) the full absolute path, but made relative, if saveExtraPath is TRUE.
    //  (For example, "c:/ck2000/appData/UnitTest/qa_data/hamlet.xml" made relative is 
    //  "ck2000/appData/UnitTest/qa_data/hamlet.xml")

    //  	1: qa_data/hamlet.xml

    //  with the filepaths as shown above.
