The FieldValueGetter class is an abstract class that serves as the base for
all FieldValueGetters. FieldValueGetters are used to get values from
a target. The details of how to execute these operations is left to the
subclasses and depends upon the type of the target object. For the most part,
the subclass ReflectionGetter will do the job, but there may be cases
where a more specific approach will yield more efficient, or more desired, results.
