Compatibilty:
I have tested the plugin with activerecord-1.14.4 on Oracle 9i

Usage:
myModelObject = MyModel.new
myModelObject.query("some sql query")
myModelObject.fetch_next_batch

For more examples, please look into the test cases.

Scope of current release:
i) Works only with (retrieval) queries. No validation of sql is done.
ii) Oracle types such as LOB, BLOB etc are not handled.
iii) Only forward iteration is supported.
