<P>
A subclass of Converter that allows specifying keys to be deleted.
<p>When a Converter is used with an entity class, secondary keys cannot be
automatically deleted based on field deletion, because field Deleter objects
are not used in conjunction with a Converter mutation. The EntityConverter
can be used instead of a plain Converter to specify the key names to be
deleted.</p>
<p>It is not currently possible to rename or insert secondary keys when
using a Converter mutation with an entity class.</p>
