Example

Feed the SchemaTrainer some objects:

var schemaTrainer = new SchemaTrainer

schemaTrainer.train({
	gender: 'male',
	name: 'Joe'
})

schemaTrainer.train({
	gender: 'female',
	name: 'Martha'
})

schemaTrainer.train({
	gender: 'male',
	name: 'Bob'
})

schemaTrainer.train({
	gender: 'female',
	name: 'Cindy'
})

console.log(schemaTrainer.toJS())

Call toJS() to return an object with the JSON Schema
