In chiefBiiko/octostep: Iterate Lists

Besides a list octostep takes a function as input, applies it to each element of the list and returns the resulting list.

1	octostep(x, func, pad = 1L, use.names = TRUE, transform.previous = FALSE)

`x`	List required.
`func`	Function with `length(formals(func))` == `2L * pad + 1L` required.
`pad`	Integer controlling how many items should be padded around the current item, must be within `1L:((length(x) - 1L) / 2L)` for the ordinary use case with `length(x) >= 2L * pad + 1L`, otherwise 1L optional.
`use.names`	If `x` has a `names` attribute, should it be used for the return value? optional.
`transform.previous`	Should the `previous` arguments of the callback take the values of previous callbacks rather than the plain values of the initial input list optional.
