remove public Fields access

[meltzow]

using public fields in classes are bad practice. Is is very hard to use a class if every field and method is public, because everything is changeable and useable. We need a encapsulation of functions.
With Eclipse refactoring support, generation of getters and setter are possible. A good workflow is, change the field to private (without refactoing) and use quickfixes to use the getters/setters.
While refactoring please take some seconds and think about the fields and his visibility. Private is not the only way. We are implementing a framework which needs to be extends with overriding classes. Somethings there is a need for protected fields.
