Subsetting method for mmkin objects

Calculation routines based on the FOCUS Kinetics Report (2006,
2014). Includes a function for conveniently defining differential equation
models, model solution based on eigenvalues if possible or using numerical
solvers. If a C compiler (on windows: 'Rtools') is installed, differential
equation models are solved using automatically generated C functions.
Non-constant errors can be taken into account using variance by variable or
two-component error models <doi:10.3390/environments6120124>. Hierarchical
degradation models can be fitted using nonlinear mixed-effects model packages
as a back end <doi:10.3390/environments8080071>. Please
note that no warranty is implied for correctness of results or fitness for a
particular purpose.
