Merge remote-tracking branch 'origin/huffman-optimization'
Improved code for case where symbol is missing from the tree
Added code to skip johns tests by setting a breakpoint if we want
Merge remote-tracking branch 'origin/huffman-optimization'
Added some optimizations that seem to have sped things up significantly
Added a open source implementation of LZW called SharpLZW
Implemented merging huffman trees
More on merging huffman trees
Added LZW encoding and extension methods.  Added test class as well.
Added LZWandHuffmanTest.cs and improved LZW test
