Lots of bug fixes, performance improvements, and minor enhancements.  More
features will be rolled out later in the 2.0.4 release.  A few unit tests still
fail, which is very frustrating, so these need to be corrected at some point in
the future.

	modified:   src/main/java/edu/ucla/sspace/common/Similarity.java

- Fixed bug in a branch of Euclidean distance (also, sped the method up)

	modified:   src/main/java/edu/ucla/sspace/common/Statistics.java

- Fixed javadoc typo

	modified:   src/main/java/edu/ucla/sspace/dependency/BreadthFirstPathIterator.java

- Clarified argument in the javadoc

	modified:   src/main/java/edu/ucla/sspace/dependency/CoNLLDependencyExtractor.java

- Added slight better error handling for bad CONLL data

	modified:   src/main/java/edu/ucla/sspace/graph/ChineseWhispersClustering.java

- Fixed bug in which logger was being used for CW

	modified:   src/main/java/edu/ucla/sspace/graph/Graphs.java

- Clarified javadoc

	modified:   src/main/java/edu/ucla/sspace/graph/SparseUndirectedGraph.java

- Added a constructor that lets the user preallocate the size of the graph,
  which is very helpful when you know you'll be making a large graph

	modified:   src/main/java/edu/ucla/sspace/graph/UndirectedMultigraph.java

- Added a constructor that lets the user preallocate the size of the graph,
  which is very helpful when you know you'll be making a large graph

- Fixed formatting issue

	modified:   src/main/java/edu/ucla/sspace/graph/io/GexfIO.java

- Added the ability to write vanilla Graph instances to Gexf.  This class is in
  serious need of an overhaul, but the Graph I/O package is a mess at the
  moment. :(

	modified:   src/main/java/edu/ucla/sspace/matrix/GrowingSparseMatrix.java

- Clarified error message

	modified:   src/main/java/edu/ucla/sspace/matrix/SparseHashMatrix.java

- Added @Override for best practices

	modified:   src/main/java/edu/ucla/sspace/text/UkWacDependencyFileIterator.java

- Added better error handling

	modified:   src/main/java/edu/ucla/sspace/util/HashIndexer.java

- Added a new constructor that lets the user pre-allocate the size of the indexer

	modified:   src/main/java/edu/ucla/sspace/util/KrippendorffsAlpha.java

- Major overhaul of the code, which is still a mess.  Added unit tests to verify
  the currently executable parts work, but there's a mysterious bug in the
  ORDINAL case which still needs to be resolved.  The other levels of
  measurement will be added during the next release.

	modified:   src/main/java/edu/ucla/sspace/util/PartitioningNearestNeighborFinder.java

- Fixed HTML bug in the javadoc

	modified:   src/main/java/edu/ucla/sspace/vector/SparseHashDoubleVector.java

- Fixed performance bug in magnitude()

	modified:   src/main/java/edu/ucla/sspace/vector/SparseHashIntegerVector.java

- Fixed performance bug in magnitude()

- Fixed case where 0-value were not being removed, which affected the contents
  of the getNonZeroIndices() array

	modified:   src/main/java/edu/ucla/sspace/vector/VectorMath.java

- Performance enhancements

	modified:   src/test/java/edu/ucla/sspace/common/SimilarityTest.java

- Added unit test to verify the bug fix to euclideanDistance

	modified:   src/test/java/edu/ucla/sspace/util/KrippendorffsAlphaTest.java

- Added unit tests for alpha values based on the examples in Krippendorff's papers.
