Sleep for a Number of Milliseconds (FTP Utility)

Demonstrates the Chilkat Ftp2.SleepMs method, which blocks the calling thread for a number of milliseconds. The only argument is the millisecond count. It performs no FTP network operation.

Background: This is a plain convenience wrapper around a thread sleep, provided so scripts and generated examples can pause without pulling in a language-specific timing API. Typical uses are inserting a short delay between polling attempts, or giving a finicky server a moment between operations. It does nothing FTP-specific.
