[trello-GPLVzh49] This is the subject

Here is a longer description of what I actually did. It could be an
entire paragraph.

* It could also include bullet points.
* Like these.

or code snippets:

+ (dispatch_queue_t)getBackendServiceDispatchQueue
{
    static dispatch_queue_t modelQueue = nil;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^
    {
        modelQueue = dispatch_queue_create("net.wooga.puzzzle-lines.backend-serivce", DISPATCH_QUEUE_SERIAL);
    });
    return modelQueue;
}
