Support Classes
The following are generally useful classes that might be used in more than one scenario. They were ussually developed in the context of a specific scenario, but should be useful in other contexts, possibly with a little modification. By publishing the classes here, implicit permission is granted for you to use these classes in your projects, modify and distribute them. You should not, however, remove the original author name. If you modify a class, add your own name as an additional author (with explanation of the modifications made, if you want), but acknowledge original authors.
We have plans for updating these support classes in the near future, but for now we are making them available here.
