Added an ugly solution.
More comments and a new command line encoder.
Removed LocationEntry.
Added command line decoder. But still something missing (sees filled up zeroes as letters itself).
Improved command line interpreter.
Added piping functionality to Decoder.java and Encoder.java (but Encoder needs a file to read from, because he needs to know the length)
Updated README.md
...
Added prettier tree printer.
Added a command to reset the prefix trees.
Presentation added.
