Add missing SchemaType Options (unique, index, etc). about typegoose

[teddis]

Hi, I'm trying to find out why Typegoose is not creating a unique index on a new model property for me. It's not even creating an index. I'm assuming it works for you! Everything in my code looks correct and the property is defined as:

@prop({ index: true, unique: true })
sessionId?: string; 

I'm using Mongoose 5.2.5, MongoDB 3.6.6, and Node 9.2.1. My model references an existing collection. I dropped the collection and it rebuilt with only _id index. I guess I'll have to debug, but hoping someone can tip me off to any other config I'm forgetting or wasn't documented? Oh I also restarted mongodb without effect, and dropping the collection several times. I've had to create the index manually in mongodb (or Robo3T), and then unique index constraint works. Thanks.

Hello!

Yes unfortunately I haven't covered all options yet, and yes all PR is appreciated! :)

Nevermind. I discovered I had to call model.createIndexes() after compiling the model to ensure the index is built. I think it would be helpful for others to add this to your README.
