* Code Janitor time! Many fixes and documenting fixes that should be
      done in the future. for the most part, this is a general code cleanup.
    * On smaller/embedded systems, the "final" keyword cleanups will have
      more of an impact than on larger systems.
    * Document missing hashCode() methods.
    * Unhide more variables to make code easier to read.
