Delete Multiple Remote FTP Files by Wildcard

Demonstrates the Chilkat Ftp2.DeleteMatching method, which deletes files in the current remote directory whose names match a wildcard pattern. The only argument is the pattern. It returns the number deleted, or -1 on failure.

Background: This is a convenience for bulk cleanup — deleting all *.tmp or *.log files in one call rather than listing and looping yourself. It operates only on the current directory and does not recurse. The count return lets you confirm how many were removed, distinct from the -1 failure signal; because deletion is permanent, double-check the pattern before running it.
