HarvestKit: A Swift framework

We use Harvest at work for time tracking and recently I needed to use the Harvest Time Tracking API. I noticed there wasn't a Swift framework listed for working with it, so I've put one together.

I'm still pretty new to Swift so it's probably not great but it's a start.

You can find the project here

You can find full documentation here

I'm really interested on feedback on what I'm doing strangely and how I can improve. I like Swift and I'm slowly getting to grips with it so any help/advice/pull requests are greatly appreciated.

Feel free to open an issue to discuss problems and fixes.

At the minute the project has the bare minimum and I will be expanding it but I wanted to get some feedback before I go any further as it's still early enough that I can break any strange habits.
