inWing -- Check if member is in a wing.
($wID, $pin = 0)
This function checks to see if a member is on the roster for a certain wing. The wing id is passed via the argument $wID and is mandatory.

This function returns true if $pin (RSID if ! $pin) is found in wing $wID. It returns false otherwise, including returning false on other failures.
