/**
 * Panel that can display the output of cvs annotate command or similar equivalent in other
 * vcs. How to use:
 * 

 * 1. Create the panel + add it into your window/panel.
 * 2.  define how to extract the data. Is done by calling add*ColumnDefinition()  methods.
 * 3.  add data addLine(Object) .. the Object needs to be of the class defined by the add*columnDefinition methods..
 * 4. display the panel.
