List/Priority version 0.04
==========================

NAME
    List::Priority - Perl extension for a list that manipulates objects by
    their priority

SYNOPSIS
      use List::Priority;

      # Create an instance
      my $list = List::Priority->new();

      # Insert some elements, each woth a unique priority
      $list->insert(2,'World!');
      $list->insert(5,'Hello');
      $list->insert(3,' ');

      # Print
      print $list->size()                   # prints 3
      while (my $element = $list->pop()) {
              print $element;
      }

DESCRIPTION
    If you want to handle multiple data items by their order of importance,
    this one's for you.

    You may retrieve the highest-priority item from the list using "pop()",
    or the lowest-priority item from the list using "shift()". If two items
    have the same priority, they are returned in first-in, first-out order.
    New items are inserted using "insert()".

    You can constrain the capacity of the list using the "capacity"
    parameter. Low-priority items are automatically evicted once the specified
    capacity is exceeded. By default the list's capacity is unlimited.

    I'd like to thank Joseph N. Hall and Randal L. Schwartz for their
    excellent book "Effective Perl Programming" for one of the code hacks.
