Checking in a version Brandes' betweeness-centrality code.  This version could
be cleaned up to use the latest util.primitive (or Trove) classes.
Added ability include stack trace in unit test output
Lots and lots of bug fixes with a few minor functionality enhancements.

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

- Added warnings for invalid KL-divergence computations

- Added Kruskal-Goodman Gamma

- Discovered Spearman's rho and Kendall's tau are both wrong (not fixed)  :(

	modified:   src/main/java/edu/ucla/sspace/common/statistics/LogLikelihoodTest.java

- Fixed implementation

	new file:   src/main/java/edu/ucla/sspace/graph/ChineseWhispersClustering.java

- Added CW clustering, but it doesn't appear to produce the same results as the
  existing code (needs investigation)

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

- Tweaked logging

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

- Made thread count based on processors instead of fixed

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

- Added partial support for weighted multigraphs.  More features are probably needed eventually

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

- Added better logging instead of printf

	new file:   src/main/java/edu/ucla/sspace/graph/io/GraphMLReader.java

- Added initial GraphML implementation for reading large GraphML files.  Only partial support is in place

	modified:   src/main/java/edu/ucla/sspace/index/DefaultPermutationFunction.java

- Fixed outstanding bug.  Not sure how the bug was there in the first place, as
  the code was currently very broken in an odd way.

	new file:   src/main/java/edu/ucla/sspace/text/AnnotatedDocument.java

- Added support for a new document that has a creation date and a label

	new file:   src/main/java/edu/ucla/sspace/text/BufferedFileListDocumentIterator.java

- Added a new iterator that pre-caches the contents of files in a file list
  using a separate thread to cut down on disk I/O

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

- Added support for a document back by a file whose contents are loaded into memory on demand

	new file:   src/main/java/edu/ucla/sspace/tools/IterativeBigramExtractor.java

- Added a tool for finding statistical associations between terms in an
  iterative pair-wise manner

	new file:   src/main/java/edu/ucla/sspace/tools/LinkClusteringTool.java

- Copied over code from the SVN branch for running link clustering from a jar

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

- Corrected the Exception to be thrown in remove()

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

- Correct a few errors in removing keys during iterator

- Fixed a bug where null was returned instead of the empty set

	new file:   src/main/java/edu/ucla/sspace/util/KrippendorffsAlpha.java

- Implemented max() and min()

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

- Made Serializable

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

- Clarified javadoc

	new file:   src/test/java/edu/ucla/sspace/graph/WeightedDirectedMultigraphTest.java

- More unit tests

	modified:   src/test/java/edu/ucla/sspace/index/DefaultPermutationFunctionTest.java

- Added some debugging output
	modified:   pom.xml

- Added support for picking up the *Tests.java unit tests

	modified:   src/main/java/edu/ucla/sspace/common/statistics/LogLikelihoodTest.java
