getch() in Rust

getch.rs

/*
 1. copy getch() into getch.c from here: http://stackoverflow.com/a/912796/3989982
 2. compile getch.c with: gcc -o libgetch.so -shared -fPIC getch.c
 3. create getch.rs with the below content
 4. compile getch.rs: rustc -L. getch.rs
 5. run it: LD_LIBRARY_PATH=. ./getch
 
 You can extract these steps into a build script (or someone can make a platform independent getch based on this)
