* You have to specialize this file by defining:
* <li><b>GetKey(value)</b> Extracts the key from a data value</li>
* <li><b>KeysEqual(hashset,key1,key2)</b> Tests wether 2 keys are equal</li>
* <li><b>DO_REHASH</b> Instead of storing the hash-values, recalculate
- * them on demand from the datavalues. (usefull if
+ * them on demand from the datavalues. (useful if
* calculating the hash-values takes less time than
* a memory access)</li>
