Demo for sourcemaps in gulp-typescript without inlining sources

Configuring the paths for sourcemaps can be a pain. This repo has examples that show how source maps can be configured with relative paths and no inlined sources. See gulpfile.js for the examples.

Sourcemaps of files in subdirectories are also working properly. This can be seen by running gulp default, gulp outdir or gulp tsconfig and opening index.html in a browser that supports source maps.

The basic rule is:

• If you don't provide the outDir option to TypeScript, the sourceRoot option of gulp-sourcemaps should be the relative path from the gulp.dest path to the source directory (from gulp.src)
• If you set the outDir option to the same value as the directory in gulp.dest, you should set the sourceRoot to ./.
• If you set the outDir option to a different value, there is no easy rule to configure gulp-sourcemaps. I'd advise to change the value of outDir if possible.
