On ARM based devices, the `gl` module may require some libraries to be re-installed:
`sudo apt-get install -y build-essential libxi-dev libglu1-mesa-dev libglew-dev pkg-config` -- see https://github.com/stackgl/headless-gl#ubuntudebian for more.

Most contribution (we imagine) would be in the form of API-compatible modules, which need not be directly included.

optional_options is just an optional parameter, in object form, which you might
want to provide to the modules.
A variety of syntaxes are supported by Image Sequencer to add multiple steps and configurations quickly for module chaining. The project supports the string syntax, designed to be compact and URL friendly, and JSON, for handling more complex sequences. This can be achieved by passing strings to `sequencer.addStep()`:

## Noise-Reduction
Noise in an image are atypical pixels that are not representing the color or the exposure of the scene correctly. This Noise Reduction module reduces the noise in the image by using either median filtering or mean filtering techniques to change the RGB value of the pixels to create a smoother and fuller image.
#### Usage
```js
sequencer.loadImage('PATH')
.addSteps('noise-reduction',options)
.run()
```
where `options` is an object with the property `method`. `options.method` can be:
* Median Filtering: Set the RGB value of the pixel to the median RGB pixel value of all adjacent pixels (maximum 8 adjacent pixels and itself)
* Mean Filtering: Set the RGB value of the pixel to the mean RGB pixel value of all adjacent pixels (maximum 8 adjacent pixels and itself)
## overlay-module
This module is used for overlaying an Image over another .
