CSOLNP fails if the sense of the constraint is reversed
Make test model that's not supposed to use derivatives actually not use them, and patch bug the faulty test model was hiding.
Manifest paths allowed for LISREL
Latent paths allowed for LISREL
GREML test script should make sure the model runs both with and without analytic derivatives.
Inelegantly coded but working implementation of analytic GREML derivatives.
Improve test organization
Improve error message
Add ability to do means paths for LISREL type models.
