Formatted from Eclipse with space indentation (2 spaces) and 120 character lines (who uses a terminal with 80 character lines for coding anymore?).
Refactored packages and classes (removed that dreadful 'Rv' and 'viewer' tokens).
Removed explicit serialVersionUID (assuming it was added during compilation).
Removed some duplication in constructors.
This is still cleanup mode, purely at a code level and file structure.
simple cleaning of some variable names and unused imports.
