The QuickHashIntSet class

INTRODUCTION
	This class wraps around a set containing integer numbers.

	Sets  can also be iterated over with foreach as the Iterator interface is implemented as well. The order of which elements are returned in
       is not guaranteed.

CLASS SYNOPSIS
       QuickHashIntSet

       QuickHashIntSet

       Methods

       o public bool QuickHashIntSet::add (int	$key)

       o public QuickHashIntSet::__construct (int  $size, [int	$options])

       o public bool QuickHashIntSet::delete (int  $key)

       o public bool QuickHashIntSet::exists (int  $key)

       o public int QuickHashIntSet::getSize (void  )

       o publicstatic QuickHashIntSet QuickHashIntSet::loadFromFile (string  $filename, [int  $size], [int  $options])

       o publicstatic QuickHashIntSet QuickHashIntSet::loadFromString (string  $contents, [int	$size], [int  $options])

       o public void QuickHashIntSet::saveToFile (string  $filename)

       o public string QuickHashIntSet::saveToString (void  )

PREDEFINED CONSTANTS
	      o QuickHashIntSet::CHECK_FOR_DUPES -If enabled, adding duplicate elements to a set (through either  add()  or  loadFromFile())  will
		result in those elements to be dropped from the set. This will take up extra time, so only used when it is required.

	      o QuickHashIntSet::DO_NOT_USE_ZEND_ALLOC	-Disables  the use of PHP's internal memory manager for internal set structures. With this
		option enabled, internal allocations will not count towards the memory_limit settings.

	      o QuickHashIntSet::HASHER_NO_HASH -Selects to not use a hashing function, but merely use a modulo to find  the  bucket  list  index.
		This is not faster than normal hashing, and gives more collisions.

	      o QuickHashIntSet::HASHER_JENKINS1 -This is the default hashing function to turn the integer hashes into bucket list indexes.

	      o QuickHashIntSet::HASHER_JENKINS2 -Selects a variant hashing algorithm.
