Multiple choice knapsack problem using or-tools

[Kyle Jensen]

Hi - new or-tools user here. 

** I'm seeking an example in which or-tools is used to solve a multiple choice knapsack problem.  

I'm embarrassed to say that my optimization background is quite limited.  So, it wasn't clear to me if the or-tools solvers could be extended easily from the 01-knapsack problem to the MCKP.

Thanks!

Kyle
