7074264: Review : Adds unit tests to sources and switches to packages tree view

[Mike Duigou]

Hello All;

I've updated my small patch to the J2SE Netbeans project to add the unit test sources. 

It also includes :

- switches the source view to "tree" layout as the package lists are too large for easy navigation.
- Updates and corrections to README file.  (new since rev "0")
- Fixes JavaDoc output path for J2SE project. (new since rev "0")

Ulf : I have opted not to make the change to the java-data-no-native.ent and java-data-native.ent files you suggested. There were too many references to these files as well as documentation to change. I will save this for an eventual reorganization of the NetBeans projects.

The webrev can be found at:

Thanks,

Mike
