check_inputs

This function checks the start_vlaues, data, availabilities, draws and fixedparams for validity.
If this function runs without error, then the inputs are valid for the maxLikelihood function.
These checks are important, because an error in the internal C++ code will cause the Rstudio session to crash.
Incidentally, if there is concern of this happening, it is recommended to run the script from the
command line, using Rscript.

Specification and estimation of multinomial logit
models. Large datasets and complex models are supported, with an
intuitive syntax. Multinomial Logit Models, Mixed models, random
coefficients and Hybrid Choice are all supported. For more
information, see Molloy et al. (2021) <https://www.research-collection.ethz.ch/handle/20.500.11850/477416>.
