Reorganize packages

[Matthias Schoettle]

Currently the packages are a bit unorganized in two ways:

• Different base packages: Model has ca.mcgill.cs.sel.ram, other stuff has ca.mcgill.sel.ram and the GUI has also ca.mcgill.ram. ca.mcgill.sel.ram should be the general base.
• In the GUI the packages sometimes don't make sense (in regards to their contents) and some contain too much stuff and should be split, e.g., views.

I propose the following structure:

• Base package: ca.mcgill.sel.ram
• The base package of model, edit should conform to the base package
• GUI base package: ca.mcgill.sel.ram.ui
  • Split specific view things and general views/components
  • ca.mcgill.sel.ram.ui.views.(structure|message|state) for Structural/Message/State View things
    • each of these has handler, handler.impl
  • ca.mcgill.sel.ram.ui.scenes for scenes (and handler, handler.impl subpackages)
  • Alternative: ca.mcgill.sel.ram.ui.handler with subpackages in there

[Matthias Schoettle]

The new message view UI will use the following structure, which fits better with what we have so far:

• ca.mcgill.sel.ram.ui.views.message
• ca.mcgill.sel.ram.ui.handler.message(.impl)

Then, in the base package (views or handler) general classes can be located.
