Code in Wiki is dated

[jackkoenig]

eg. https://github.com/ucb-bar/chisel-tutorial/wiki/Basic%20Types%20and%20Operations

class FullAdder extends Module {
  val io = IO(new Bundle {
    val a    = UInt(INPUT, 1)
    val b    = UInt(INPUT, 1)
    val cin  = UInt(INPUT, 1)
    val sum  = UInt(OUTPUT, 1)
    val cout = UInt(OUTPUT, 1)
  })

...

I'll fix it up

@jackkoenig created a PR on chisel-tutorial-wiki repo. Hopefully it's ok, at the very least it's way more up-to-date than it was

Looks fixed on wiki now
