* A bag stores an object and a count of the number of occurrences of the object.
*
* The following implementations are provided in the package:
*
* - HashBag - implementation that uses a HashMap to store the data
*
- TreeBag - implementation that uses a TreeMap to store the data
*
*
* The following decorators are provided in the package:
*
* - Synchronized - synchronizes method access for multi-threaded environments
*
- Unmodifiable - ensures the bag cannot be altered
*
- Predicated - ensures that only elements that are valid according to a predicate can be added
*
- Transformed - transforms each element added to the bag
*
- Collection - ensures compliance with the java.util.Collection contract
*
