Transition from Imap.FetchChunk to Imap.FetchRange

Provides instructions for replacing deprecated FetchChunk method calls with FetchRange. Swift

func chilkatTest() {
    var success: Bool = false

    let imap = CkoImap()!

    // ...
    // ...

    var startSeqNum: Int = 1
    var count: Int = 5

    let failedSet = CkoMessageSet()!
    let fetchedSet = CkoMessageSet()!

    // ------------------------------------------------------------------------
    // The FetchChunk method is deprecated:

    var bundleObj: CkoEmailBundle? = imap.fetchChunk(startSeqNum: startSeqNum, count: count, failedSet: failedSet, fetchedSet: fetchedSet)
    if imap.lastMethodSuccess == false {
        print("\(imap.lastErrorText!)")
        return
    }

    // ...
    // ...

    bundleObj = nil

    // ------------------------------------------------------------------------
    // Do the equivalent using FetchRange.
    // Your application creates a new, empty EmailBundle object which is passed 
    // in the last argument and filled upon success.

    var headersOnly: Bool = false

    let bundleOut = CkoEmailBundle()!
    success = imap.fetchRange(headersOnly: headersOnly, seqnum: startSeqNum, count: count, bundle: bundleOut)
    if success == false {
        print("\(imap.lastErrorText!)")
        return
    }
