		Right now source maps are located via this rule: the preprocessors appends
		".map" to the file name, and if that file exists it loads and includes it.
		This plug-in supports both inline and external source maps.

		Inline source maps are located by searching "sourceMappingURL=" inside the javascript
		file, both plain text and base64-encoded maps are supported.

		External source maps are located by appending ".map" to the javascript file name.
		So if for example you have Hello.js, the preprocessor will try to load source map from
		Hello.js.map.

		This is very simple but should work in the majority of cases for standard usage (e.g. with typescript).
