Implementation of Huffman compression algorithm
Platforms: Linux, Windows

Build:

'make' produces 'encode' & 'decode' executables:

	'encode' -- compresses any input file using Huffman algorithm:
	$ encode <input-file> <output-file>	
	
	'decode' -- decompresses input file to the original one:
	$ decode <input-file> <output-file>
	
'make test' produces 'test' executable:
	'test'   -- runs equality tests on files mentioned in main.cpp
				(default files are stored in a folder 'testing'):
				encode 'input' 'encoded'; decode 'encoded' 'decoded; 
				then compares 'input' with 'decoded'
