Implementing an evolving IVF dataset

This script demonstrates how to add/remove elements from an IVF dataset in a rolling fashion. The key is to use a Hashtable as DirectMap type and remove with IDSelectorArray. Removal cost is then proportional to the number of elements to remove instead of number of elements in the dataset.
