The algorithm allows any kind of weights (costs, frequencies), including non-numerical ones. The {0, 1, ..., n-1} alphabet is used to encode message. Built tree is n-ary one.

The algorithm is based on a set of template classes :
- Cell(SYMBOL, WEIGHT),
- Node(SYMBOL, WEIGHT),
- InternalNode(SYMBOL, WEIGHT),
- TerminalNode(SYMBOL, WEIGHT),
- BasicHuffmanTree(SYMBOL, WEIGHT, ARY),
- LoadedHuffmanTree(SYMBOL, WEIGHT, ARITY),
- DriedHuffmanTree(WEIGHT, ARITY).
The user should use only LoadedHuffmanTree and/or DriedHuffmanTree classes.
LoadedHuffmanTree requires (as input data) the symbols and their weights.
DriedHuffmanTree requires (as input data) only the weights.

The program contains the following tests :
* Creating Loaded 5-ary Huffman Tree from data vector with char-symbols and int-weights;
* Creating Loaded 24-ary Huffman Tree from data vector with char-symbols and int-weights;
* Creating Loaded Binary Huffman Tree from data vector with char-symbols and int-weights;
* Creating Dried (Unloaded) Binary Huffman Tree from data vector with int-weights (Fibonacci sequence);
* Creating Dried (Unloaded) Binary Huffman Tree from data file with int-weights;
* Creating Loaded Binary Huffman Tree from data file with char-symbols and int-weights;
* Creating Loaded Binary Huffman Tree from data vector with string-symbols and float-weights;
* Creating Loaded Binary Huffman Tree from data vector with AAA-symbols and BBB-weights;
* Encoding and Decoding vector-message using 5-ary Huffman Tree;
* Encoding and Decoding string-message using 5-ary Huffman Tree;
* Encoding and Decoding vector-message using Binary Huffman Tree;
* Encoding and Decoding string-message using Binary Huffman Tree
