+  This file contains functions to create and manipulate hash-tables.
+  Before using the hash initialize it by calling hash_table_init function.
+  The function takes pointer to hash function as the last parameter.
+  URGENT: the result of the hash function must not be greater than size of the hash table.
+  To insert a key-value pair, use hash_table_insert function.
+  To lookup a value by the key, use hash_table_lookup function.
+  After using the hash, delete it by calling hash_table_free function.
