[IDEA] Snippet for export default class ES6

[AndrewJGregory]

With every new component I type export default class ${className} extends React.Component {}. I'd love to add a snippet for this, however I'm a bit unsure on how to do it. I've forked this repo and added the appropriate snippet in snippets/JavaScript (JSX).cson, but I don't know what needs to be in done in terms of testing or actually integrating it. Some guidance would be appreciated.
