cumsum_kbn signature is too restrictive

[stevengj]

The signature cumsum_kbn(v::AbstractVector{T}) where T<:AbstractFloat seems too restrictive. What about summing Complex{Float64} or SVector{Float64,3}, for example?

sum_kbn accepts any type, which seems more reasonable. (If you pass something like an array of integers, it will still work, just wasting some computations.)

It also seems to assume 1-based indexing. Generalizing that to allow OffsetArrays would be nice as well.

OK -- revisiting.
What signature is recommended?

cumsum_kbn(v::AbstractVector)
cumsum_kbn(v::AbstractVector{T}) where {T<:Number}
etc
