/**
 * Class DRC_ITEM
 * is a holder for a DRC (in Pcbnew) or ERC (in Eeschema) error item.
 * It is generated when two objects are too close (DRC)
 * or two connected objects (pins) have incompatible electrical types (ERC).
 * There are holders for information on two items.  The
 * information held is the board coordinate and the MenuText for each item.
 * Also held is the type of error by number and the location of the MARKER.
 * A function is provided to translate that number into text.
 * Some errors involve only one item (item with an incorrect param) so
 * m_hasSecondItem is set to false in this case.
