Test comparator method for ordering sequence params...
Implementing chained comparator methods, following http://www.codejava.net/java-core/collections/sorting-a-list-by-multiple-attributes-example.

Adding overridden toString methods to FOV class (and eventually others) to aid in debug and metadata generation...
Added overriden toString() methods in all classes concerning sequenced acquisition
Testing chained comparator method of sorting
Deal with case in sequence when one (or more) of three main tables (FOV, TimeCourse, Filter) is not used.
This involves creation and use of a CurrentLightPath class, created when LightPathPanel is instantiated and modified whenever controls in LPP change.
This will serve as a template for the CurrentFOV class which will also need to be implemented, if only for displaying the well map panel.
Such classes will also be useful for metadata saving...
