This is a golang tool to extract mongodb schema. The main steps are:

1. List all collections from mongdodb database

2. Handle collection one by one

	1. Select 100 documents and analysis document's fields type according object real type. Using []bson.D as result type: `	var results []bson.D 

	err := c.Find(bson.M{}).Limit(MaxTryRecords).Sort("-_id").All(&results)`

	1. For slice []interface{}, also handle at most 100 records.

	1. Handle bson.D as embedded document.

Depends on 

1. [https://github.com/globalsign/mgo](https://github.com/globalsign/mgo "golang mongodb driver")

2. [https://gopkg.in/urfave/cli.v1](https://gopkg.in/urfave/cli.v1 "command line go application")
