 * determine how that memory is allocated by declaring the u_malloc
 * and u_free functions globally in your main.c file (here the examples
 * use the standard C malloc library functions but you could use the
 * block allocator, a mixture of the two, or something of your own):
 *
 * ( u_malloc must return carry flag set if allocation successful )
 * void *u_malloc(uint size) {
 *    return(malloc(size));   * lib function malloc sets carry *
 * }
 *
 * ( u_free must ignore addr == 0 )
 * void u_free(void *addr) {
 *    free(addr);             * lib function free ignores 0 *
 * }
 *
 * If implemented in assembler, use the labels _u_malloc and _u_free
 * with HL as the parameter and return value.  PUBLIC both labels to

/*** DOUBLY LINKED LIST

Items are stored in an ordered list.  Each list has a current pointer
that can point at: a specific item, before the list or after the list.
The list iterator is ListSearch, which searches from the item pointed
at by the current pointer and stops when the matching function
reports a match or when the current ptr points past the end of the list.

In the following:

   void *delete <->  void [] (*delete)(void *item)
   void *match  <->  char (*match)(void *item1, void *item2) return 0 if =

/*** HEAP (PRIORITY QUEUE)

The heap is an array of void* with indices 1..N used to store items.  Items in a
heap are stored in a special order that allows single item insertion and ordered
extraction quickly.  When an array is sorted in this special order, it is said to
posses the heap property.

Heapify can be used to convert an unsorted random array into a heap with the heap
property.  HeapAdd is used to add items to a valid heap incrementally.  HeapExtract
pulls items out of the heap one at a time in order.

Besides returning the smallest (min heap) / largest (max heap) item in the heap,
HeapExtract will also write the extracted item to the end of the array.  If all
items in an array are extracted one after the other, the array, after all
extractions, will be sorted in ascending order (max heap) or descending order
(min heap).  This is an implementation of heapsort.

In the following:

     void *compare  <->  char (*compare)(void **item1, void **item2)
       return negative if item1>item2 for max heap (extract largest item first)
       return negative if item1<item2 for min heap (extract smallest item first)

     NOTE ON VOID** Addresses within the array are being passed not array contents

Maximum array size (N) is 32767.  You provide the array and N, the number of items
in the heap.  N will automatically be modified as items are added and removed from
the heap.
