Public constructor RWTPtrHashSet<T>(unsigned (*hashFun)(const T&),
size_t buckets = RWDEFAULT_CAPACITY);
Constructs an empty hashing set. The first argument is a pointer to a user-
defined hashing function for items of type T . The table will initally have
buckets buckets although this can be changed with member function
resize() .
