Changes

The above program needs an input file to compress and decompress text in. For the purposes of testing, the Gutenberg press' complete works "Complete Works of Shakespeare " was used as an input text file (http://www.gutenberg.org/files/100/100-0.txt) because it represents a large enough body of text to actually have perceptible run times for compression. Increases in the size of the data used are created through copying one full version of the text in the last iteration of testing and appending it to the end of the text file (so one Shakespeare's complete works becomes two back to back, two becomes four, etc).
