Built a Helper program to automate some tasks for the maintainers.

Has an automation task for style checking due to the fact that he gradle checkstyle plugin requires us to store the google_style.xml which would require license additions.

+# Apache Wave
+
+Welcome Apache Wave Maintainer.
+
+This document is your cheat sheet to the resources which are spread around the Apache Wave
+repositories and websites. Many of the Apache specific documentation will be on the Wiki linked
+below while non-apache related items will be on the website.
+
+### Helpful Links
+
+- [Confluence Wiki](https://cwiki.apache.org/confluence/display/WAVE/Maintainer+Documentation)
+- [Maintainer Website](https://incubator.apache.org/wave/maintainers)
+
+
+### Helper Tool
+
+In the Apache Wave repository is a helper tool which is designed to make our lives easier. The 
+tool is ever growing to meet the demands of the project. The maintainers website is the stable 
+location for documentation on the tool.
+
+**Required: You must have go 1.7+ installed.**
+
+With go installed you can run the tool with: 
+
+- `go run helper/cli.go`
+- `go run helper/cli.go -h`
+- `go run helper/cli.go -help`
+
+It will produce files in the `.helper` directory which should not be used for permanent storage
+ as `-clean` will remove the entire folder.
+
+**Note: Once new website has been made and published formal docs will be located in the 
+maintainers section.**
