Caveats
This doesn't support the entire API and the API has been changed in a few places to fit better in a node.js environment. For easier distribution, this currently includes build artifacts (.dll and .lib as well as headers) for loot-api.
Async
There is support for running commands asynchronously. The was this is implemented is unusual though: When instantiating an "asynchronous" LOOT instance, a second process is created. The LOOT instance in the initial process acts as a proxy, relaying instructions to the second process where they will be queued and processed in sequence.
