14/** 
15 * a door to the REPL
16 * 
17 * Usage: it works with a LightServer (see project razweb). You can {@link #attachTo} to an existing server or {@link create} a new, dedicated one.
18 * 
19 * If all you need in an app is the scripster, create one on a port of your choice, with no extra services.
20 * 
21 * To customize interaction, you can mess with the Repl - that's the actual interaction with the REPL
