/**
* ListMergeModel is a model for interactively comparing and merging two list of entries
* of type T. It maintains three lists of entries of type T:
* <ol>
* <li>the list of <em>my</em> entries</li>
* <li>the list of <em>their</em> entries</li>
* <li>the list of <em>merged</em> entries</li>
* </ol>
*
* A ListMergeModel is a factory for three {@link TableModel}s and three {@link ListSelectionModel}s:
* <ol>
* <li>the table model and the list selection for for a {@link JTable} which shows my entries.
* See {@link #getMyTableModel()} and {@link ListMergeModel#getMySelectionModel()}</li>
* <li>dito for their entries and merged entries</li>
* </ol>
*
* A ListMergeModel can be ''frozen''. If it's frozen, it doesn't accept additional merge
* decisions. {@link PropertyChangeListener}s can register for property value changes of
* {@link #FROZEN_PROP}.
*
* ListMergeModel is an abstract class. Three methods have to be implemented by subclasses:
* <ul>
* <li>{@link ListMergeModel#cloneEntryForMergedList} - clones an entry of type T</li>
* <li>{@link ListMergeModel#isEqualEntry} - checks whether two entries are equals </li>
* <li>{@link ListMergeModel#setValueAt(DefaultTableModel, Object, int, int)} - handles values edited in
* a JTable, dispatched from {@link TableModel#setValueAt(Object, int, int)} </li>
* </ul>
* A ListMergeModel is used in combination with a {@link ListMerger}.
*
* @param <T> the type of the list entries
* @see ListMerger
