Remove use of numba package. Use item values in [0,1,2,3] instead of [-3,-1,1,3]. Allow use of std as an alternative to mu when doing model analysis or running simulations. Generate RT and choice curves for data and simulations on the same plots for comparison. Remove fine grid search. Receive data file names as arguments in load_data_from_csv(). run_simulations() returns distances to target instead of item values. In dyn_prog_test_algo.py, write simulated data to CSV files. Fix mutation and crossover tools in genetic algorithm. Save best individual in genetic algorithm. Add code for running analysis of a single model. Add code for generating likelihood plots for model parameters.
