/**
* This gulpfile will copy static libraries and a index.html file as well as
* merge, babelify and uglify the rest of the javascript project.
*
* TODO:
* - Separate media, libs and src with different watchers.
* - Media and libs should only be copied to dist if they are different sizes.
*
* The expected project is to be laid out as such:
*
* ├─┬ src
* │ ├─┬ libs
* │ │ ├── tween.min.js
* │ │ ├── pixi.min.js
* │ │ └── jquery.min.js
* │ ├─┬ media
* │ │ ├── audofile1.wav
* │ │ └── picture1.png
* │ ├─┬ subfolder
* │ │ └── class1.js
* │ ├── main.js
* │ └── index.html
* └── gulpfile.js
