 // A lot of the more complicated sync logic is implemented in the
 // ModelTypeSyncProxyImpl that owns the ModelTypeEntity.  We can't unit test it
 // here.
 //
 // Instead, we focus on simple tests to make sure that variables are getting
 // properly intialized and flags properly set.  Anything more complicated would
 // be a redundant and incomplete version of the ModelTypeSyncProxyImpl tests.
