Added instantiation of a List<Object> as placeholder for
IEnvironmentalVariable object from JBIDE-15598 jira issue; Issue #14
Added some helper getters for the variables, as placeholders, in case
the operations will be required in this model, from actions in the
current view. Issue #2
Added missing return value, which was hendering "OK" button from working
properly.  (Must have been lost in the erroneous merge sequence this
morning.) Issue #4
Updated model and view for primary configuration wizard to reflect use
of the IEnvironmentalVariable object, and
IApplication.getEnvironmentalVariables() method. Issue #14
Update to support issue #3
Updated to reflect some changes in how the processing will function.  Removed reference to connection(s) because the model should update the primary wizard's binding context and then subsequently update the application configuration when processing everything else.  Issue #12
Please enter the cemmisome changes in how the processing will function.  Removed reference to connection(s) because the model should update the primary wizard's binding context and then subsequently update the application configuration when processing everything else.  Issue #11 and #14
Updated Edit view to handel null pointer exception when there is an empty list provided.  This should be handled by disabling the view and attaching a listener which will allow the button to be activated when the variable list is not empty. Issue #11
Update to support some form of check on list emptiness upon generation of the page, so appropriate buttons will be visible, or not. Issues #3 #4
