add Cassie meshes in the Matlab simulation

[haoyuhaoyuhaoyu]

Hi, I use the C-Frost to generate the solution, but the output of the analyze_solution.m is only a simplified Cassie model, how can I add the Cassie's meshes to the model( just like the results. in the paper 'Rapid Bipedal Gait Design Using C-FROST with Illustration on a Cassie-series Robot')? :)

Can you successfully run the program? When I run the command './program --initial 'res/init.json' --options '../ipopt.opt' --data 'res/data.json' --bounds 'res/bounds.json' --solution '../local/output/sol.json' ', I got the error "terminate called after throwing an instance of 'std::length_error'
what(): basic_string::_M_create"
