Hash list class for pointer data  |

TFPHashList implements a fast hash class. The class is built for speed, therefore the key values can be shortstrings only, and the data can only be non-nil pointers.
if a base class for an own hash class is wanted, the TFPCustomHashTable class can be used. If a hash class for objects is needed instead of pointers, the TFPHashObjectList class can be used.
