Added prototypic support for query by example queries to SimpleJpaRepositories. Clients can use an Example Object to wrap an existing prototype entity instance that will be used to derive a query from. Would be great if we could unify this effort with the infrastructure from DATAMONGO-1245.
We convert a given Example to a set of and combinded Predicates using CriteriaBuilder. Cycles within associations are not allowed and result in an InvalidDataAccessApiUsageException. At this time only SingularAttributes are taken into concern.

We now support querying entities by providing a sample of the given object holding compare values.
At this time only
SingularAttributesare considered and the given sample object must not contain cycles.By default
nullvalues will be ignored nevertheless usingNullHandler.INCLUDEwill match those usingisNull.It is possible to ignore properties based on their property path from
