/**
 * @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
