Test fixed size arrays

[ernestmc]

Adds unit test cases for fixed sized arrays with different data types.
Note that currently some tests are not passing and will be addressed in future pull requests like #59 which is pending review.

To run the tests:

./gradlew test

Here's a snapshot of the current status of the tests:

Thanks for the contribution!

I only have one comment regarding this. I think this is good to have even if not all the tests are passing; we can fix them in future PRs.

What's the difference between this test and a simple byte array? Should we add a byte array test too?

[ernestmc]

Good point. I will see to add tests for byte arrays, although according to this comment ChannelBuffer is the preferred way.

Found this in the RawMessage interface:

  /**
   * @deprecated replaced by {@link #setInt8(String, byte)}
   */
  void setByte(String name, byte value);

  /**
   * @deprecated replaced by {@link #setInt8Array(String, byte[])}
   */
  void setByteArray(String name, byte[] value);

  /**
   * @deprecated replaced by {@link #setUInt8(String, byte)}
   */
  void setChar(String name, short value);

  /**
   * @deprecated replaced by {@link #setUInt8Array(String, byte[])}
   */
  void setCharArray(String name, short[] value);

Added the tests for byte arrays and they are failing too.

Thanks @ernestmc; you already have my approval :)
