-This file contains additional configuration written by modules in the NetBeans IDE.
-The configuration is intended to be shared among all the users of project and
-therefore it is assumed to be part of version control checkout.
-Without this configuration present, some functionality in the IDE may be limited or fail altogether.

-Properties that influence various parts of the IDE, especially code formatting and the like. 
-You can copy and paste the single properties, into the pom.xml file and the IDE will pick them up.
-That way multiple projects can share the same settings (useful for formatting rules for example).
-Any value defined here will override the pom.xml file value but is only applicable to the current project.
