Mimetype handling and identification

This is mostly used by the UI to figure out which icons to show for different filetypes.

It does a best effort guess to figure out which icon to show, which might not always come out very accurate.

It should be updated over time with relevant file types and mime types and it is by no means a definitive representation of all available file types.

Glossary

• type - A media/MIME type http://en.wikipedia.org/wiki/Internet_media_type
• group - A group of types that corresponds to a more global type of media (ex: plaintext, image, video, audio, etc)
• group name - the display name for a given group
• group label - the label used to identify a group in fileGroups.json and groupNames.json

API

Options object used by various methods

The methods that take this object as a parameter will always try to use the type if available. If the type is not available or is undefined, it will use the file extension as a fallback. You can also provide a fallback file name from which the extension will be extracted if not provided.

 * @prop {string} type Content MIME type
