Description: Fit and compare nonlinear mixed-effects models in
        differential equations with flexible dosing information
        commonly seen in pharmacokinetics and pharmacodynamics
        (Almquist, Leander, and Jirstrand 2015
        <doi:10.1007/s10928-015-9409-1>). Differential equation solving
        is by compiled C code provided in the 'rxode2' package (Wang,
        Hallow, and James 2015 <doi:10.1002/psp4.12052>).
