=head1 FUNCTIONS

=head2 cache

This caches the currently selected IMAP folder into a specified Mail::Cache.

Three arguements are taken. The first that is taken is Mail::IMAPTalk object.
The second is the Mail::Cache object. The third is if it should forcefully
regenerate the the entire cache instead of just the new stuff.

    my $mc=Mail::Cache->new();
    $mc->init('My::Module', 'imap', 'someAccount', 'INBOX');
    if(!$mc->{error}){
        my %returned=Mail::IMAPTalk::MailCache->cache($imap, $mc, 0);
        if(!$returned{error}){
            print "Error: ".$returned{error}."\n";
        }
    }else{
        print "Failed to init the mail cache.\n";
    }
