Besides KmerTrie.java and Kernelmatrix.java, you should also submit
KMerTrieTest.java and KernelMatrixTest.java including the documentations
(purposes) for the tests. It's not required to use JUnit testcase, but
your tests must be well organized and well documented. Messy test cases
will recieve zero marks even if they are correct.
