Change the Remote Directory (CWD)

Demonstrates the Chilkat Ftp2.ChangeRemoteDir method, which changes the current working directory on the FTP server. The only argument is the remote directory path.

Background: This sends a single CWD with the path exactly as given; Chilkat does not split a multi-level path into one CWD per segment, so whether a/b/c works in one call depends on the server. A relative path moves from the current directory, while an absolute path (leading /) is resolved from the root according to the server's conventions. Confirm the result with GetCurrentRemoteDir when it matters.
