Convert Rust data structures to/from (relatively) idiomatic Clojure data in memory using JNI.
See test/src/lib.rs for a usage example.
```rust
struct {
number: i32,
names: Vec
becomes
clojure
{:number 3
:names ["foo" "bar"]}
```
Vec<u8>
representing
binary data, you should annotate or wrap these fields with
serde_bytes, or you will end
up with a vector of java.lang.Short
, which probably isn't very
efficient.
