/**
This file contains macros to create and manipulate hash-tables.
In order to define a hash use HASH_TABLE or STATIC_HASH_TABLE macro.
DO NOT FORGET to define KEY_TYPE##_hash and KEY_TYPE##_equal functions, they will be used
for internal purposes.
Before using the hash initialize it by calling HASH_INIT macro.
To insert a key-value pair, use HASH_INSERT macro.
To lookup a value by the key, use HASH_LOOKUP macro.
After using the hash, delete it by calling HASH_FREE macro.
