Simple, fast, one-file linear material cutting calculator. It uses greedy-kind of algorithm and doesn't yield global optimum solution, but the solutions are good enough to compete with other 1D-cutters available online. The algorithm is written in non-recursive way and is much faster than many other cutters available. It is also able to accept and compute solutions for very large and diverse inputs.
