* Modified `evaluate_network` to process nets with multiple outputs, but still only returns 1 output (first output of given NN)
* Added 2D relu function (left 1D relu for HornNets)
* Added function to handle classification NNs
  * `discretize_classifier_output` converts real number output to "indices" based on input thresholds
  * `impose_classifier_constraint` multiples classifier output column with other columns based on map
* Extended character length of network filename variable to allow longer names
* Added names, default settings, load function, evaluate function, CLI, and make instructions for new network named `adept`
* Added git-LFS pointers to new network namelist files
* Updated `data/README.md` to include new repository for `adept` weights and biases (currently a private repo)
