Simple usage

Check the test folder for a fast implementation of the library. Remember to:

• Annotate the @SpringBootApplication class with the @EnableHandledBackrelations annotation;
• Implement a BackrelationHandler as in CompanyCityBackrelationHandler test;
• Annotate a @ManyToMany(mappedBy=frontRelationField) field with a @HandledBackrelation annotation setting the correct BackrelationHandler bean type value.
