Server side JavaScript dependency resolution

Purpose: Easing maintenance of JavaScript files and their inclusions in web pages by server-side dependency resolution. If at the top of a.js you include the comment // requireScript b.js and at the top of b.js you say // requireScript c.js then JSResolver`s method .asTags(`a.js`) will give you e.g. which you can then stick Straight into your web PaGE. Circular dependencies Between JS files are forbidden and raise an exception.
