Implemented wrap command (with docs)
Allow newline when rebuilding index scout in unlink command

When I was testing 'procss wrap', I noticed that the index
scout had two @import statements on a single line. This
can spell trouble. It looked as if the -n switch used on
the echo udating the index scout in the 'unlink' command
was the culprit. Removed.
Merge branch 'feature/wrap' into develop
Implement unwrap command (with docs)
Remove lib command. wrap and unwrap do the job better
