Generate friendly creator method for DAO base class

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Use an abstract base class for a JDBC DAO

Please provide any additional information below.

It's inconvenient to get an instance of the DAO class converted to the base 
class type when using @Table(extend=...)

  final X x = (X)DAO.create(Y.class, dataSource);

It would be nice for the generated DAO code to include its own create() method:

  public static X create (final DataSource dataSource) {
    return (X)jlibs.jdbc.DAO.create(Y.class, dataSource);
  }

Thus making it possible to write the cleaner:

  final X x = X.create(dataSource);

Right now, it's obviously possible to get this by simply putting that method 
into the base class manually, but it would be friendlier for the API to 
generate it.

@Table(extend=X.class)
class Y{
}

class X extends DAO<Y>{
}

then the generated DAO will be:

class _X extends X{
    ....
}

if I add the mentioned static method to _X,

then you need to do:
    final X x = _X.create(dataSource);

i.e you are directly referencing the generated class _X in your source. I think 
it would be bad idea to use generated class _X directly in the code.

what is your opinion?

You're right.  That would not be an improvement...  As a convenience method, 
it's nice to have, but it has to be added to the "extend" class.
