+	 * @brief New enumerator for inventory types
+	 * 
+	 * This is intended as a replacement to the above EType.
+	 * EType will be phased out in favor of this enum.
+	 *
+	 * This enum acts as a bitfield, which This has several
+	 * useful properties for filtering:
+	 *
+	 *   1. The inventory item's type can be compared by either
+	 *      equality or bitwise AND. Bitwise AND allows a quick
+	 *      check to see whether the type is one of multiple
+	 *      possible types.
+	 *
+	 *   2. It allows for a fast hierarchical organization, by
+	 *      defining a broad type (e.g. NIT_BODYPART) whose
+	 *      value is the bitwise OR-ing of several more specific
+	 *      sub-types (e.g. NIT_SKIN|NIT_HAIR|...).
+	 *
