		### leveldown#batch(operations[, options], callback)
		<code>batch()</code> is an instance method on an existing database object. Used for very fast bulk-write operations (both put and delete). The `operations` argument should be an `Array` containing a list of operations to be executed sequentially, although as a whole they are performed as an atomic operation inside LevelDB. Each operation is contained in an object having the following properties: `type`, `key`, `value`, where the type is either `'put'` or `'del'`. In the case of `'del'` the `'value'` property is ignored. Any entries with a `'key'` of `null` or `undefined` will cause an error to be returned on the `callback`. Any entries where the type is `'put'` that have a `'value'` of `undefined`, `null`, `[]`, `''` or `new Buffer(0)` will be stored as a zero-length character array and therefore be fetched during reads as either `''` or `new Buffer(0)` depending on how they are requested.
