REPL

[danilopedraza]

I need a REPL. Right now there is a basic REPL that evaluates single lines. I need some features:

• [x] Getting previous commands like in the terminal
• [x] Searching previous commands like in the terminal
• [x] Multiline evaluation (this looks difficult)
• [x] Remember assigned values (currently it does not have memory)

There are two line reading libraries that can help me in this task: Rustyline and Linefeed.

It seems like Rustyline is the most complete of the two (and the most popular).

Rustyline is nice!

I added naive implementations for all the necessary features.
