Title: KIJIMR-13. Seal kiji-mapreduce.

This commit makes the following changes to the kiji-mapreduce API:

1. All abstract classes and interfaces are marked with inheritance
annotations (@Inheritance.Extensible or @Inheritance.Sealed) that
indicate whether the audience for that class/interface should or
should not extend/implement the class/interface.
2. Classes in general are made final when possible.
3. When possible, the access modifiers for constructors have been made
more restrictive (private or package-private). Factory methods have
been provided with public access modifier.
