Invoke JUnit assertEquals with Argument Order (expected, actual)

The JUnit API documents assertEquals as taking the expected argument
before the actual argument.  Failure to adhere to this can result in
very confusing test failure messages.

For example in testTransformOneValue 'old' contains 'A' and 'expected'
contains 'a'.  If the implementer does not lower-case the key, the
failure message is as follows if the argument order is
(actual, expected):

EtlTest > testTransformOneValue FAILED
    java.lang.AssertionError: expected:<{A=1}> but was:<{a=1}>
        at org.junit.Assert.fail(Assert.java:88)
        at org.junit.Assert.failNotEquals(Assert.java:834)
        at org.junit.Assert.assertEquals(Assert.java:118)
        at org.junit.Assert.assertEquals(Assert.java:144)
        at EtlTest.testTransformOneValue(EtlTest.java:27)

This is very confusing as "was:<{a=1}>" is exactly what we were hoping
the result would be.

sublist: add to track

* Issue #152: Made simple-cipher more approachable by splitting test classes in a more sensible way and making clear which steps they relate to.

* Changed SimpleCipherTest to use the junit Rule annotation for expected exceptions. Changed variable names in SimpleCipherTest to be more descriptive and moved the test cipherThrowsWithEmptyKey from step three to step two.

* Added HINT.md which explains how to run only one test class.

* Changed HINT.md in simple-cipher to refer to the actual test file names and not to contain the same information as in SETUP.md

Added parameters test name annotation Atbash DecodeTest. 

Resolves #161.

Removed Ignore annotation from first test in queen-attack.

Added Ignore annotation to all tests but the first one in all-your-base.

Deprecate binary, hexadecimal, octal, trinary

* Added format string to @Parameters annotation in and (to make them more descriptive) changed names of variables and tests in:
  * AtbashTest,
  * BinaryTest,
  * OctalTest,
  * PigLatinTest,
  * RaindropsTest,
  * RomanNumeralsTest,
  * ScrabbleScoreTest.
* Removed repeated word in format string for PiglatinTest and ScrabbleScoreTest.

Make Oracle JDK default for Debian distros

Without this instruction, the system continues to use the default OpenJDK.  This is confusing since we instruct the practitioner to install Oracle's JDK.
