+/* Notes due to finish in the future are held in a queue (linked list)
+ * in time order. Qhead points to the head of the list and addtoQ() 
+ * adds a note to the list. The unused elements of array Q are held
+ * in another linked list pointed to by freehead. The tail is pointed
+ * to by freetail. removefromQ() removes an element (always from the
+ * head of the list) and adds it to the free list. Qinit() initializes
+ * the queue and clearQ() outputs all the remaining notes at the end
+ * of a track.
+ * Qcheck() and PrintQ() are diagnostic routines.
