java.lang.Object
  extended byorg.metacosm.util.CollectionFactory
public class CollectionFactory
extends java.lang.Object

This factory encapsulates the creation of Collections. A configuration file is used to get Collections returned by *Pref* methods. The configuration gile is 'CollectionFactory.properties'.
Example: 

 Collection myCollection;

 myCollection = CollectionFactory.createPrefCollection();
 myCollection = CollectionFactory.createStandardCollection("ArrayList");
TODO:
CHECK FOR ERRORS!!!
clean up code and optimize
improve documentation
improve type checking in methods
create optimized version for Pref (using cache)
create synchronized versions
create version with load factor?
add initial capacity and load factor to properties?
create method to change load factor at runtime?
Create method to re-init properties at runtime (needed to change pref collections at runtime)

Version:
1.2.2
