Depending on the use, all functions may not be required
* ``get/set, K, Kdiag``: compulsory
* ``dK_dtheta``: necessary to optimize the model
* ``dKdiag_dtheta``: sparse models, BGPLVM, GPs with uncertain inputs
* ``dK_dX``: sparse models, GPLVM, BGPLVM, GPs with uncertain inputs
* ``dKdiag_dX``: sparse models, BGPLVM, GPs with uncertain inputs
* ``psi0, psi1, psi2``: BGPLVM, GPs with uncertain inputs
