Petri net simulator for rust

This is a rust binding to my petri net simulator written in C. The rust binding tries to be safer than the C API, and simplifies interactive editing and reaction to changes. The example should do exactly the same as in the C version.

For more information look at the documentation or have a look at the C API.

Also have a look at the petri net editor, which makes use of the whole API, and helps you understand, how it works.
