+ * USB Human Interface Device (HID) Class report descriptor processing routines. This file allows for the easy
+ * parsing of the complex HID report descriptor, which describes the data that the device transmits to the host.
+ *
+ * The processed report is presented back to the user application as a flat structure containing each report
+ * item's IN, OUT and FEATURE (if desired) items along with each item's attributes.
+ *
+ * This library portion also allows for easy setting and retrieval of data from a HID report, including devices
+ * with multiple reports on the one HID interface.
+ *
+ * By default, FEATURE reports and IN/OUT reports with constant data are ignored in the HID report when processed
+ * to save on memory. This can be overridden by defining the HID_ENABLE_FEATURE_PROCESSING or
+ * HID_INCLUDE_CONSTANT_DATA_ITEMS tokens in the user project makefile, passing them to the compiler via the -D
+ * switch.
