Remove gen-class since project.clj :main is enough
Remove unused project
Update README with usage
Cleanup comments in core.clj
Remove deps in jawsome-dsl.core
Reorganize plans in jawsome-cli
Lots of little roadmap items.

 - Integration with clojure.tools.cli
 - Delimiter is now specified at CLI, not in pipeline
 - Header is now pretty printed (no parens, delimited by delimiter)
 - Header may go in the first line of xsv file, OR header may go to a separate file
 - You may now specify filenames for input/output paths, which default to *in* and *out* if unspecified
