Create Task Schema

[vontell]

Create a datatype / schema for a task. This must include the format for a task in terms of the task title, subtasks, what's complete, due date, (location ?), etc.

I was thinking of something such as the following:

{
    title: string,
    difficulty: double,
    due: date | null,
    completed: boolean,
    note: string | null,
    location: null | {
        lat: double,
        lng: double
    },
    subtasks: [
        {
            title: string,
            completed: boolean
        }, ... 
    ]
}

In the Java implementation, this will include methods to get, set, construct, and save / load to and from a JSON format. @tpatel1781 what do you think? Any other fields you can think of?
