## Usage

```js

const BlockArray = require('block-sequence').BlockArray

const init = require('block-sequence-mongo')

const MongoClient = require('mongodb').MongoClient

// Initialise the Mongo Block Sequence Driver

init({ url: 'mongodb://localhost/sequences', client: MongoClient, options: { } }, (err, driver) => {

    if (err) throw err

    // Ensure the sequence exists

    driver.ensure({ name: 'my-sequence' }, (err, sequence) => {

        if (err) throw err

        // Create a block array containing 1000 ids per block (defaults to 2 blocks)

        var idGenerator = new BlockArray({ block: { sequence: sequence, driver: driver, size: 1000 } })

        // Grab the next id

        idGenerator.next((err, id) => {

            if (err) throw err

            console.log(id)

        })

    })

})
