* Abstract converter class that parents both the JPA and Eclipselink
* converters.
*
* Key notes:
* - any metadata mapped from XML to this class must be compared in the
* equals method.
* - when loading from annotations, the constructor accepts the metadata
* accessor this metadata was loaded from. Used it to look up any
* 'companion' annotation needed for processing.
* - methods should be preserved in alphabetical order.
