Evaluation of structural and residual variability models
problem.eval is a secondary function called during estimation runs. It
evaluates the structural model and the residual variability model at given
point estimates and at given values of the time variable.
is typically not called directly by users.

A list containing the following levels:
A vector of numerical estimates of numerical parameters.
A logical variable, indicating whether the analysis is a direct grid search or not.
An indicator whether checks should be performed to validate function inputs.
Return a list of two elements:
A vector of model evaluations at all requested time points (all states values are concatenated into a single vector).
A vector of residual variability related to the model evaluations.
