* @brief Map implementation for maps with a pre-defined size.
* @details
* Can be initialized with desired maximum size.
* Iterator is used to access <key,value> pair and iterate through map entries.
* Complexity O(n).
* @warning Iterators return a non-const key_t in the pair.
* @warning A User is not allowed to change the key, otherwise the map is corrupted.
