Create Zip in a BinData Object

Recursively appends files in a directory tree and writes a zip archive into a Chilkat BinData object. C

    // See Global Unlock Sample for sample code.

    // the filepath passed to NewZip does not matter.

    // Append a directory tree.  The call to AppendFiles does
    // not read the file contents or append them to the zip
    // object in memory.  It simply appends references

    // is called, the referenced files are streamed and compressed
    // into the .zip output file (or BinData object).
