Order.LineItems.properties missing from LineItem

[vincejairam]

I don't see the properties [JsonProperty("properties")] as part of the LineItem class. It seems to be missing. I added the following

    [JsonProperty("properties")]
    public IEnumerable<NoteAttribute> LineProperties
    {
        get;
        set;
    }

to get those properties for additional instructions that the customer is requesting for the item in the store.
