+ * @title:GcalRangeTree
+ * @stability:stable
+ *
+ * #GcalRangeTree is an augmented AVL tree implemented to be
+ * able to handle ranges rather than point values. This tree
+ * is used by @GcalWeekGrid to store events according to their
+ * start and end minutes, and thus all the data structure was
+ * optimized to handle a limited subset of values.
+ *
+ * In the future, we may need to extend support for broader
+ * range values, and move away from guint16 in function params.
+ *
+ * # Ranges
+ *
+ * Conforming to the overall standard of iCal and Calendar,
+ * the start of a range is inclusive but the end of the range
+ * is always exclusive.
