HierarchyTreeNode: Initial commit.
MyController: Add 'updateNodes' method. 
Currently only walking the nodes in the JTree and printing to screen.
MyController: Add to 'updateNodes' method.
Basic implementation of the code that will be used to set the
'HierarchyTreeNode' to a specific Mode.
MyController: Update 'setActiveRoles' and 'updateNodes' methods. 
- The 'setActiveRoles' method now accepts an ArrayList as input, rather
than having LHSTable hard coded in. 
- The 'updateNodes' method has been tweaked to set the mode first,
rather than waiting to set it inside the Enumeration.
HierarchyTreeNode: Tweak the 'setMode' method. 
This method will only set the mode if the specified mode is 'greater'
than the currently selected mode.
MyController: Shuffle 'setSelected' roles code.
MyController: Fix 'updateNodes' method. 
This will now correctly downgrade 'SELECTED' nodes to 'ACTIVE'.
HierarchyTreeNode: Remove greater than requirement from 'setMode'.
MyController: Initial code for the 'updateParentNodes' method.
HierarchyTreeNode: Swapped one mode for two. 
- The new enum modes are 'activeMode' and 'selectedMode'.
- Setup new setter/getter methods.
MyController: Reflect changes in HierarchyTreeNode.
- Renamed 'updateNodes' to 'updateChildNodes', matching the existing
'updateParentNodes' method. 
- Update the 'updateChildNodes' method to use the new 'ActiveMode' and
'SelectedMode' in HierarchyTreeNode.  
- Update 'updateChildNodes' to use a different method signature, test
the nodes for 'active' or 'selected' rather than directly setting the
mode.
MyTreeRenderer: Update to reflect HierarchyTreeNode. 
- Rendering based on the active mode, and selected mode of each node. 
- Moved setting the font into the 'selected' switch.
MyController: Implement the 'updateParentNodes' method.
MyTreeRenderer: Add support for partial selected/active nodes. 
- Remove debugging print to screen messages. 
- Tweaked the 'orangeColor'.
MyStatusBar: Initial commit.
MyController/MyView: Add in a status bar.
MyTreeRenderer: Changed rendering of partial selection to use
setBackgroundNonSelectionColor instead.
MyController: Tweaked colors.
