Predicting choice shares

I've loaded a function called predict_mnl() that we can use to predict choice shares for a new set of products. predict_mnl() takes two inputs:

a model object produced by mlogit
a data frame describing the products that we want to predict shares for

Inspect products to see what features these four cars have. products is not large, so you can simply type its name to print the full data frame to the console.
Use predict_mnl() to predict shares for those two products. You will need to set the first input to m1 and the second input to products.
Print the shares to the console by typing shares.
