I no longer use DbGenerator. Should DbGenerator be deprecated?

The new MergerContext stuff is a million times better for my
purposes: to add new tables/columns to the database if the model
changed and the database didn't.
I am very much in favor of doing that. In practical terms it means
switching Modeler / Ant / Maven to the MergerContext, and add support
for some missing databases. Wonder if we still need to preserve
"generate all" mode.

    I think the merger stuff (nice name) has some limitations related to
    the order the different tokens are performed preventing us from
    deprecating DbGenerator.

    Within a single entity, different tokens are ordered correctly, but
    there may be some problems with several dependent entities and
    relationships between them. Before this is fixed/improved, I still
    think we need DbGenerator. Sorry.

    Fair enough. BTW, I am in need of an auto-schema-bootstrap
    functionality (maybe we do it with another DbAdapter decorator??) I
    guess this feature can be done based on DbGenerator as well, as it is
    most useful for the new databases. As e.g. blindly dropping columns in
    an existing database may not be what the user wants.

    I think I found an easy solution to this now by adding all the
    AddRelationshipToDb tokens at the end. It seem to work for my model..
