return value: **`sequencer`** (To allow method chaining)
## Method Chaining
Methods can be chained on the Image Sequencer:
* run() can not be in the middle of the chain.
* If the chain starts with loadImage() or loadImages(), the following methods are
applied only to the newly loaded images.
Valid Chains:
```js
sequencer.loadImage('red').addSteps('invert').run(function(out){
//do something with otuput.
});
sequencer.addSteps(['ndvi-red','invert']).run();
et cetra.
```
Invalid Chains:
```js
sequencer.addSteps('invert').run().addSteps('ndvi-red');
```
## Multiple Images
Image Sequencer is capable of handling multiple images at once.
