/**
 * TPriorityList class
 *
 * TPriorityList implements a priority ordered list collection class.  It allows you to specify
 * any numeric for priorities down to a specific precision.  The lower the numeric, the high the priority of the item in the
 * list.  Thus -10 has a higher priority than -5, 0, 10 (the default), 18, 10005, etc.  Per {@link round}, precision may be negative and
 * thus rounding can go by 10, 100, 1000, etc, instead of just .1, .01, .001, etc. The default precision allows for 8 decimal
 * places. There is also a default priority of 10, if no different default priority is specified or no item specific priority is indicated.
 * If you replace TList with this class it will  work exactly the same with items inserted set to the default priority, until you start
 * using different priorities than the default priority.
 *
 * As you access the PHP array features of this class, it flattens and caches the results.  If at all possible, this
 * will keep the cache fresh even when manipulated.  If this is not possible the cache is cleared.
 * When an array of items are needed and the cache is outdated, the cache is recreated from the items and their priorities
 *
 * You can access, append, insert, remove an item by using
 * {@link itemAt}, {@link add}, {@link insertAt}, and {@link remove}.
 * To get the number of the items in the list, use {@link getCount}.
 * TPriorityList can also be used like a regular array as follows,
 * <code>
 * $list[]=$item;  // append with the default priority.  It may not be the last item if other items in the list are prioritized after the default priority
 * $list[$index]=$item; // $index must be between 0 and $list->Count-1.  This sets the element regardless of priority.  Priority stays the same.
 * $list[$index]=$item; // $index is $list->Count.  This appends the item to the end of the list with the same priority as the last item in the list.
 * unset($list[$index]); // remove the item at $index
 * if(isset($list[$index])) // if the list has an item at $index
 * foreach($list as $index=>$item) // traverse each item in the list in proper priority order and add/insert order
 * $n=count($list); // returns the number of items in the list
 * </code>
 *
 * To extend TPriorityList for doing your own operations with each addition or removal,
 * override {@link insertAtIndexInPriority()} and {@link removeAtIndexInPriority()} and then call the parent.
