(C) SFTP Synchronize Directory Tree - Download

Demonstrates how to download files to synchronize a local directory tree with a remote directory tree. The SyncTreeDownload method recursively descends the remote directory tree and downloads files based on existence, last-mod date/time and/or size differences.

    // mode=0: Download all files
    // mode=1: Download all files that do not exist on the local filesystem.
    // mode=2: Download newer or non-existant files.
    // mode=3: Download only newer files. If a file does not already exist on the local filesystem, it is not downloaded from the server.
    // mode=5: Download only missing files or files with size differences.
    // mode=6: Same as mode 5, but also download newer files.
    // mode=99: Do not download files, but instead delete remote files that do not exist locally.
