/**
* Given an input object maps to an appropriate output object. A mapper may
* variously provide a mapping between types, object instances or keys and
* values or any other form of transformation upon the input.
*
* <p/>All mapper implementations are expected to:
* <ul>
* <li>Provide stable results such that for any {@code t} the result of two
* {@code map} operations are always equivalent. ie.<pre>
* Foo one = mapper.map(a);
* Foo two = mapper.map(a);
*
* assert one.equals(two) && two.equals(one);
* </pre></li>
* <li>Equivalent input objects should map to equivalent output objects. ie.<pre>
* assert a.equals(b); // a and b are equivalent
*
* Foo x = mapper.map(a);
* Foo y = mapper.map(b);
*
* assert x.equals(y); // their mapped results should be as equivalent.
* </pre></li>
* <li>The mapper should not modify the input object in any way that would
* change the mapping.</li>
* <li>When used for aggregate operations upon many elements mappers
* should not assume that the {@code map} operation will be called upon elements
* in any specific order.</li>
* </ul>
*
* @param <R> the type of output objects from {@code map} operation. May be the
* @param <T> the type of input objects provided to the {@code map} operation.
* same type as {@code <T>}.
