/*  Why isn't there a LoadItem() call here?
 *
 *  At the time of initial design the circumstances under which an item entry will be loaded are unclear.
 *  It is virtually guaranteed that item entries will need to be loaded when a character is loaded as the character's
 *    inventory (list of items) will be necessary.
 *  It is undecided wether some, all or no items in the world and not on a character will be saved to the database.
 *    If they are saved it is likely that many items will be loaded all at once - possibly based on location data
 *    (x,y,z,sector), possibly based on some other criteria.
