Filter

A FileAsset is a file based asset. Assets, for now, are from the local file system but there is no reason an asset could not from the cloud via a URL, or a database.

A Filter is reponsible for processing a single asset.

A TaskProcessor processes one or more assets and directly set properties on a task. For example commonJisfy, loadFiles and writeFiles are task processors as they manipulate multiple assets. loadFiles also sets the initial assets for a task.
