A way to use compiled Rust code as native functions in Java.

1. Create a Java file that has public static native methods
2. Compile that file to a header file using javac -h . ClassName.java
3. Start up a Rust library project
   1. The main file must be lib.rs
   2. In the Cargo.toml file, there should be a dependency for jni = "0.19.0" and a lib section where crate-type = ["cdylib"]
   3. The functions in the Rust file must match the ones in the header file compiled earlier with the same parameters and parameter types
   4. The Rust code should then run like normal and output a Java result (if a return value is needed)
   5. Perform a cargo build on the project
4. Make the connection using a static code block in Java and grab the DLL file from the Rust project and use System.load() to load the DLL

Not sure how this could get used in the future. The linking becomes one of the most time consuming parts of the operation, then, calling the native method also creates a performance hinderance. I'd probably have to discover other places where this integration could be used.
