 It restarts target node process when any of required files changes (as standard `node-dev`) but shares [Typescript](https://github.com/Microsoft/TypeScript/) compilation process between restarts. This significantly increases speed of restarting comparing to `node-dev -r ts-node/register ...`, `nodemon -x ts-node ...` variations because there is no need to instantiate `ts-node` compilation each time.
