Simple improvements to get rid of reflective call warning
Ignore target/
Proof that stuff doesn't work
More tests
Cleanup of vampire records.

  1) Made row protected so it does not leak.
  2) Removed the Workaround class to allow lubs to work and nice error messages.
  3) Introduced a restriction that explicit types must be user defined. Implicits should convert rows to those types. Generic version not yet done.
