PermutationTestInputFormat --> edited for permutation test
PermutationTestRecordReader --> edited for permutation test
RunsTestRecordReader --> removed uneeded globals. edited to only look for runs up or down, depending on user preferences. Now also skips the entry after a run, to implement standard chi squared. This is suggested in knuths book 'the art of computer programming'
PermutationTest --> set up for permutation test. tested successfully
RunsTest --> added max and min vals
SlapDash --> added handling for permutation test, added handling for new runs test. Cleaned up code to make it more standardised between each test
UtilArrays --> added printArray method
