org.apache.hadoop.mrunit.testutil.ExtendedAssert

[Jim Donofrio]

org.apache.hadoop.mrunit.testutil.ExtendedAssert is only used by our 
test code and really belongs under src/test/java instead of the code we 
distribute. The code is just a few convenience methods for the JUnit 
assert methods which arent that useful considering 4 of the 5 methods 
are for int's and runTest does more than the assertListEquals method. I 
think we should move the class to src/test/java and stop distributing 
it. Any thoughts?
