The IO class can be used to read and write to and from the console.
## Static Methods
### IO.print(obj[, obj2, obj3...])
Prints any number of things to the console and then prints a new line character. If you don't pass it a string, it will be converted to a string for you. When passed multiple things, Wren outputs one after another.
> IO.print("I like bananas")
I like bananas
> IO.print("Oranges", 10)
Oranges10
>
### IO.write(obj)
Prints a single thing to the console, but does not print a new line character afterwards. If you pass it something that isn't a string, it will convert it to a string.
> IO.write(4+5)
9>
In the above example, the result of `4+5` is printed, and then the prompt is printed on the same line because no new line character was printed afterwards.
### IO.read(prompt)
Reads in and returns a line of text from the console. Takes a single string to be used as a prompt. Pass an empty string for no prompt. Note that the returned line of text includes the new line character at the end.
