Conform to a uniform style

We need to convert to a single style for formatting. This has been discussed in the mailing list and as of this point, there is only one vote for tabs over spaces. I will be undertaking this task Wednesday unless anyone can provide reasoning for tabs over spaces that has not already been mentioned in the mailing list discussion. I will be adapting the Lucene style http://people.apache.org/~rmuir/Eclipse-Lucene-Codestyle.xml because that was the first explicit style mentioned in the archive. The specific style can also be discussed until Wednesday. I hope any discussions about the styling can also be complete by Wednesday morning.
