Collections

This library contains a number of collections which I have found useful. Some of the more interesting classes included are the following:

• Heap Set (either Min or Max heap)
• History Set (contains only the most recently added X elements)
• Wrappers for collection change notification
• Sorted Array List (guaranteed to maintain sort order of elements inserted)
• Case Insensitive Hash Map (for Strings)
• Composite List (presents the contents of one or more lists as a single list, optionally sorted)
