/**
 * Removes boilerplate when working with Hibernate.  History behind this:
 *
 * In scala, if you add an annotation to a var or case class param, it will put it on the field/getter/and setter.
 *
 * Many java annotations frameworks work with field OR getter/setter, but don't allow both
 *
 * Hibernate is an example of this.  Some annotations are expected on fields but not methods, and vica-versa
