* Changed eslintrc to be JSON file (Most projects use JSON version)
* Added .eslintignore to ingore node_modules from subdirectories such as examples
* Ran eslint --fix examples to fix all examples
* Added npm script for running eslint against examples
* Added npm script for running eslint against generated *out* code
* Hooked npm scripts into travis ci to prevent examples from becoming inconsistent with future PR's

browsers, such as IE 11, that doesn't have native support for WebAssembly.
