Reduce a list to a single value by iteratively applying a binary function

Inspired by reduce() from the purrr package

reduce(.x, .f, ..., .init)

`.x`	A list or atomic vector.
`.f`	A 2-argument function. The function will be passed the accumulated value as the first argument and the "next" value as the second argument.
`...`	Additional arguments passed on to `.f`.
`.init`	If supplied, will be used as the first value to start the accumulation, rather than using `x[[1]]`. This is useful if you want to ensure that `reduce` returns a correct value when `.x` is empty. If missing, and `x` is empty, will throw an error.
