Added my changes that allow for long walks instead of just int walks
Updated the README, and added deployment stuff to pom.xml
Fixed a long-standing synchronization bug in TwoKeyCompanion
Updated the github site-maven-plugin, which was broken at 0.9
Cleared memory in the close() method of TwoKeyCompanion

on with references to the objects), we need to clear the memory when we're done, or we end up
growing enormously huge by the end of a long series of runs.
Moved the dumper thread out of the inner class, to resolve some unchecked exceptions in client code
Added build.sbt, removed fork info from README
Updated version in pom.xml
Merge pull request #6 from matt-gardner/master
