AsyncImporter class

An interface for importers that resolves URLs in @imports to the contents of Sass files.

Importers should override toString to provide a human-readable description of the importer. For example, the default filesystem importer returns its load path.

This class should only be extended by importers that need to do asynchronous work. It's only compatible with the asynchronous compile() methods. If an importer can work synchronously, it should extend Importer instead.

Subclasses should extend AsyncImporter, not implement it.
