/** ***************************************
SequenceEntry is a minor helper class used exclusively by HighlightDisplay.
Each SequenceEntry widget is one line in the HighlightDisplay::settingsUi()
tab.  The constructor is called by HighlightDisplay::addNewSequence().
The class keeps track of its sequence, its color, and whether or not it has
been removed.
