/**
 * <p><b>Purpose</b>: To build and populate the database for example and testing purposes.
 * This population routine is fairly complex and makes use of the population manager to
 * resolve iterated objects as the employee objects are an interconnection graph of objects.
 *
 * This is not the recommended way to create new objects in your application,
 * this is just the easiest way to create interconnected new example objects from code.
 * Normally in your application the objects will be defined as part of a transactional and user interactive process.
