It's kinda CRUDdy... but don't let that scare you.
* `upsert(id, data)` - creates or updates based on existence in DB (use this)
* `upsert(id, data[, oldId])` - creates or updates based on existence in DB (use this)
* modifies `createdAt` and or `updatedAt`
* `create(id, obj)` - same as above, but fails if the object exists
* `save(data)` - (just don't use this, please) creates or updates based on presence of ID
* `save(data[, oldId])` - (just don't use this, please) creates or updates based on presence of ID
* `destroy(id)` - mark a record as `deletedAt` from DB
* `get(id)` - grab one by id
* `find(attrs, opts)` - grab many by indexable attributes
