//    Int2Int HashMap is a representation of the HashMap for integer keys and integer data.
//    Supported hashmap type in this module(key/data): integer -> integer
//    Most of the functions if the int2int HashMap are implemented as external functions.
//
//    Public functions:
//      <f_EPTF_int2int_HashMap_DumpByID> - Dump the content of a hash table by ID.
//      <f_EPTF_int2int_HashMap_Dump> - Dump the content of a hash table.
//      <f_EPTF_int2int_HashMap_DumpAll> - Dump the content of every hash table.
//      <f_EPTF_int2int_HashMap_New> - Creates a new hashmap.
//      <f_EPTF_int2int_HashMap_GetID> - To get the ID of the hashmap from the name.
//      <f_EPTF_int2int_HashMap_Delete> - Deletes the hashmap.
//      <f_EPTF_int2int_HashMap_DeleteById> - Deletes the hashmap by ID.

//      <f_EPTF_int2int_HashMap_Erase> - Erases an element from hashmap.
//      <f_EPTF_int2int_HashMap_Clear> - Clear all elements from hashmap.
//      <f_EPTF_int2int_HashMap_Size> - Returns the size of hashmap. Size = the used buckets
//      <f_EPTF_int2int_HashMap_MaxSize> - Returns the maximum size of hashmap(largest possible size).
//      <f_EPTF_int2int_HashMap_CallHashFunc> - Calls the hash function of a given hashmap.
//      <f_EPTF_int2int_HashMap_Empty> - Check whether the hashmap is empty. true if the hash_map's size is 
//      <f_EPTF_int2int_HashMap_BucketCount> - Returns the number of buckets used by the hash_map.
//      <f_EPTF_int2int_HashMap_Begin> - To get the first element of hashmap. 
//      <f_EPTF_int2int_HashMap_Next> - To get the next element of hashmap.
//
//   Deprecated functions:
//      <f_EPTF_int2int_HashMap_Init> - Initializes the hash table. DEPRECATED!!! Use <f_EPTF_HashMap_init_CT> instead!
