Availability:C-language interface function

hash_table_t PL_new_hash_table(int size, void (*free_symbol)(void *n, void *v))

Create a new table for size key-value pairs. The table is resized when needed. If you know the table will hold 10,000 key-value pairs, providing a suitable initial size avoids resizing. The free_symbol function is called whenever a key-value pair is removed from the table. This can be NULL.
