	@brief The PotentialSelectorDialog class
	This dialog is used when user try to connect
	two existing potential together.
	The dialog ask to user to make a choice between
	the properties of the two existing potential,
	to apply it for the new potential.

	Each constructor have a QUndoCommand parent_undo for parameter
	If parent_undo isn't null, when user click on OK button,
	the dialog will use the parent-undo
	as parent of the undo command that describe the changes.
	If parent_undo is null, the created undo-command is push
	to the undo stack of the parent diagram of a conductor in potential.
	else we apply the change without a QUndoCommand.

	the static function chosenProperties,
	open a dialog who ask user to make a choice between the given
	properties
